Yuvaraj Tankala and Joseph K Paul, 5th-semester B Tech Computer Science and Engineering students of SRM University-AP, Andhra Pradesh, India has worked with Dr Manikandan V M, Assistant Professor in Computer Science and Engineering Department on a research project and their research paper “A Content-based Image Retrieval Scheme with Object Detection and Quantized Color Histogram” got accepted for publication in the International Journal of Computational Science and Engineering.
Content-based image retrieval (CBIR) is an active area of research due to its wide applications. Most of the existing CBIR schemes are concentrated to do the searching of the images based on the texture, colour, or shape features extracted from the query image. In this manuscript, we propose an object detection based CBIR scheme with quantized colour histograms. In the proposed scheme, the meaningful objects will be identified from the query image by using you only look once (YOLO) object detection techniques and the quantized histograms of each of the object categories. The object lists, their count, and the area covered by the objects along with quantized colour histograms will be used during feature matching to retrieve the related images from the large image pool. The experimental of the proposed scheme is carried on the Corel 1K and Caltech image dataset. We have observed an average precision of 0.96 during the experimental study which is quite high while comparing the precision from the well-known existing schemes.
To retrieve relevant images from a large image pool, we use content-based image retrieval (CBIR) schemes. In a CBIR scheme, the properties of the query image will be matched with the properties of the images in the image pool. The images which are very close to the given query image will be returned by the CBIR scheme. Most of the existing CBIR schemes use colour, shape and texture properties for image comparison. In the proposed scheme, we use an object detection-based approach with quantized colour histograms to retrieve the relevant images from the image pool.
The real-life applications of the proposed scheme are listed below:
● In the fashion designing and textile industry, CBIR systems can be used to find the existing designs.
● The CBIR systems are useful in crime prevention by retrieving similar crime scenes or the images of criminal persons based on the query image.
● Professional web designers or poster designers want to retrieve relevant images depends on the specific context that they are working.
● To retrieve similar medical images with the relevant treatment details in a computer-assisted diagnosis system.
The team currently continue their research work in the same domain to come up with a content-based image retrieval system that will return the relevant images by understanding the relationships among the objects in the image. The classes of the objects in the scene and their properties also will be considered along with the relationship between the objects in the scene.
The 12th edition of the widely popular University Distinguished Lecture Series delved into the pertinent relationship between Science, Engineering and Technology. During the distinguished lecture, “Science-Engineering-Technology Synergy for Sustainable Growth”, Prof Indranil Manna well explained the correlation between the streams and how scientists, engineers and industry experts should work together for maximum societal benefits. Prof Indranil Manna, a JC Bose fellow of DST, is currently the Vice-Chancellor of BIT Mesra. The event took place on September 24, 2021, in virtual mode.
In his address, Prof Indranil Manna asserted that India is no longer a poor country but a mighty economic power with a 3 trillion dollar economy. “We are considered as one of the strongest nations of the world today, not because of the population or because of the youth living in the country, but we are the ones who could send mission to mars at the cheapest cost, and also successfully identified the existence of water on the surface of the moon. Further, we are one of the very few nuclear harnessing nations of the world,” said Prof Manna.
Science began its journey in order to find out the truths of nature. “Why?”- this question is the driving force behind Science. Though Science unravels nature and truth primarily through curiosity or need inspired acts, and the occasional outcome is significant earth-breaking discoveries, sometimes it needs technology to prove it. On the other hand, Engineering deals with “How?” and for Technology, the question is “What?”. Engineering produces certain products and devices by specific designs and inventions. However, what is absolutely essential for the society is Technology, knowledge through the path of knowing ‘why’ and ‘how’ to know ‘what’ sells. Thus, Prof Manna prescribes SET, a conjugation of Science+Engineering+Technology, as the way forward for maximum societal benefits.
Prof Manna explained that innovation means new ideas, creative thoughts, new imaginations in the form of a device or method. It is incremental, cross-disciplinary, directed and translational. Innovation matures itself via Engineering or Technological interventions. Further, sustainability is a composite concept that means the ability to maintain the desired rate or level, avoiding depletion of resources, energy or disturbing the related ecosystem.
Engineering and Technology are the key factors to sustainability. Engineers are not technicians meant only for routine production, maintenance or testing. Instead, Engineering applies the principles of science and logic to develop viable solutions to societal aspirations and challenges. The core of engineering lies in the translation, fundamental concepts to design, develop, fabricate, exploit, analyse, model, stimulate and predict,” Prof Manna elaborated.
Government of India’s Technology Vision-2035 focuses on developing the quality of life of each Indian. Science is pursuing the truth relentlessly regardless of its necessity or immediate scope of application. It provides clues, if not answers and extends as far as imagination goes. Engineering is all about enabling and providing solutions borrowing from the fundamentals of science. Technology is the last mile for societal benefit, based on scientific discovery and engineering inventions and innovations.
India is a great innovator and showcasing continuous gradual progress in it. In the Global Innovation Index (GII), India ranks 48 (2020), making it into the top 50 for the first time. Prof Manna believes that India has enough talent and potential to make it into the top 10. “Let us ensure that Science-Engineering-Technology in India complement each other and flourish together so that our society soon achieves the desired culture, growth and prosperity,” Prof Manna Concluded.
In his welcome address, Prof D Narayana Rao, Pro-Vice-Chancellor, SRM University-AP, said that the development and use of Science & Technology are critical for the achievement and sustenance of various sectors. The importance of Science and Technology to modern society and the role of the technologically educated population in promoting social and environmental developments have long been recognised. Science and technology are considered the most effective means to enhance the growth and socio-economic developments of nations. Moreover, the universalism of science and the globalisation of technological production and trade offer unprecedented opportunities for focused cooperation for scientists, engineers and the institutions that employ them to further progress in sustainable development. Even, National Education Policy-2020 advocated multidisciplinary, multi-institutional research for sustainable development.
In his concluding remarks, Prof V S Rao, Vice-chancellor, SRM University-AP, congratulated Prof Indranil Manna on delivering such a motivating lecture. He further honoured him by presenting a memento.
Dr Anil K Suresh, Associate Professor, Department of Biological Sciences, and his team from SRM University-AP recently developed a see-through transparent (with 85% above transmittance) biotemplate which they derived from the fish scale wastes to substitute the extensive usage of eco-unfriendly disposal plastic cuvettes for UV-Visible Spectroscopy measurements in the spectrum of 350-900 nm. UV-Vis spectroscopy is a versatile analytical tool used to examine the nature of various synthetic, biological and clinical molecules for pharmaceutical and environmental applications. The team members demonstrated the practical on-biotemplate analysis of diverse analytes such as DNA, proteins, nanoparticles, organic dyes, bacteria, BSA assay and dye-degradations.
Dr Anil claims that the large-scale development of the biotemplate can resolve several issues in performing sustainable research; for instance, generates huge demand for fish scales as a resource stratagem otherwise causative of foul smell and disease propagation when discarded. Second, the use of non-biodegradable plastic cuvettes can be minimized for routine analytics and third, unlike plastic cuvettes that demand 500-fold analyte our biotemplate allows the analysis at a very low 10 microlitre volumes, making it feasible to analyse expensive, rare, and high-risk analytes. Dr Anil K Suresh owns the copyrights for this pathbreaking invention by being granted an Indian patent. This work is accepted for publication in the prestigious Journal of “Green Chemistry” by the Royal Society of Chemistry. Read the full paper here.
Adding to the mechanistic, Dr Anil said, “naturally acquired droplet retaining ability for over 30 minutes against gravity while vertically positioning the biotemplate supported such ultra-low volume measurements and monitoring of chemical reactions in-situ”. Interestingly, the same ability allows the retrieval of the analytes after completion of the analysis, crucial for precious analytes. Dr Anil says the best part is that the transparent biotemplate can be discarded back into the environment post-usage without any hesitation as the biotemplate is completely biodegradable.
Further, the research group demonstrated ease in large-scale production by generating ~3000 bio templates at an affordable price. Dr Anil emphasised that this low-cost, plastic-free, use-and-throw biodegradable transparent biotemplate stemmed from food waste as a bioresource stratagem has huge potential in routine scientific and pharma UV-Vis analytics and he will very soon bring this product to the scientific community as a sustainable science solution.
Dr Anil Suresh concluded that this breakthrough conception would not have been possible without the rigorous efforts of his team and the continuous support from the university management, who are also encouraging and willing to support Dr Anil to establish his own start-up within the University. Dr Anil Suresh thanked his group members Ms Divya Parimi, Mr Chandra Bhatt, Mr Tharun Bollu and Ms Madhura, his collaborators Dr Malli and Mr Jacob. Dr Anil’s team especially thanked the management of SRM University-AP; the President Dr P. Sathyanarayanan for his generous support, Prof D Narayana Rao, Pro-Vice-Chancellor for his constant untiring encouragement, motivation and support in all his scientific endeavours, and the Vice-Chancellor Prof V S Rao for his kind support.
Swikriti Khadke, Pragya Gupta, and Shanmukh Rachakunta from third-year Computer Science Engineering have published a research paper titled “Efficient Plastic Recycling and Remold Circular Economy using the Technology of Trust – Blockchain” along with their mentors from SRM University-AP Dr Jatindra Kumar Dash, Dr Goutam Kumar Dalapati and Dr Sabyasachi Chakrabortty in the peer-reviewed journal Sustainability.
Global plastic waste is increasing rapidly. The strategic management of plastic waste and recycling can preserve environmental species and associated costs. The utilization of plastic can be done by introducing Blockchain during plastic waste recycling. Automation for the segregation and collection of plastic waste can effectively establish a globally recognizable tool using Blockchain-based applications. Collection and sorting of plastic recycling are feasible by keeping track of plastic with unique codes or digital badges throughout the supply chain. Efficient recycling technology is essential to reduce plastic pollution. Many technologies have been employed to enhance plastic recycling. Among them, blockchain is promising for plastic recycling and circular economy (CE). Blockchain, a distributed ledger, consists of some ordered blocks which are unchangeable. This can be considered an exemplary way to push the transactions of their customers under the same blockchain technology. The research group used machine learning techniques to predict plastic generation globally so that they could see the impact it will make in the coming future. The students have used ARIMA – Auto-Regressive Integrated Moving Average for the study.
The potential idea is to utilize an approach wherein recyclers can keep track of generated waste as it moves through the various chains. A platform that works by tracking recycling activities across a local recycling supply chain on the Blockchain. When this will be publicly available, consumers can also use the ledger info to make more informed purchasing decisions. The Blockchain can be utilized to track individual items through the recycling supply chain by creating physical markers like QR codes.
The suggested Blockchain-based platform can be implemented in various nations with an autonomous waste collector and storage system. This process can be expanded to individual collectors and storage systems. The novel process will be created by incorporating a reward-based Blockchain scheme with the collaboration of global businesses and local waste collectors. The proposed model further allows the effective sharing of databases among various supply chains to create a CE.
Talking about the social implications of the research, the students firmly believe that the study will result in the introduction of new technology in the recycling industry and promote awareness about technology in rural areas. Developing a platform and implementing blockchain and other facilities will be the focus of these young innovative brains of SRM University-AP in the forthcoming days.

Dr Nimai Mishra, Assistant Professor, Department of Chemistry, SRM University-AP, Andhra Pradesh, along with his research group comprising of students pursuing PhD under him, Ms V.G.Vasavi Dutt and Mr Syed Akhil has published a research article titled Cesium Lead Bromide Perovskite Nanocrystals as a Simple and Portable Spectrochemical Probe for Rapid Detection of Chlorides in the Journal ChemistrySelect (Publisher: Wiley-VCH on behalf of Chemistry Europe, Impact Factor-2.2).
Chloride anions are widely abundant in water and when they combine with calcium, potassium, and magnesium, they form chloride salts. However, the higher concentrations badly affect the environment by causing severe dehydration and even plant death. High concentrations of sodium chloride exhibit the potential of corrosive damage thereby releasing toxic metals from plumbing fixtures. Hence, there is a need to monitor the concentration levels of chloride salts in water. Several techniques like titration, spectrophotometry, ion chromatography, electrochemistry, etc have been reported to date. Despite the high accuracy and precision of these techniques, they involve expensive instrumentation and is out of reach from on-site detection. Hence, it is necessary to look for simple, portable, and cost-effective strategies for the detection of chlorides in the water.
In this article, Dr Mishra’s research group demonstrated that the wide spectral tunability of CsPbBr3 perovskite nanocrystals (NCs) via instantaneous and facile anion exchange, make them a suitable candidate for chloride detection. Rapid anion-exchange processes between CsPbBr3 perovskite NCs and different chloride solutions were carried out in ambient conditions. The resultant anion-exchanged CsPbCl3-xBrx NCs preserved the structural properties and exhibited a remarkable blue shift in photoluminescence spectra. This forms a basis for the detection of chloride ions in water. This has been applied with the limit of detection up to 100 µM. The detection strategies were not only limited to the direct addition of chloride solutions to NCs, but they also showed a visual colour change under UV light when the chloride solution is drop-casted on CsPbBr3 films that are deposited on glass substrates. Furthermore, the detection strategy is established by drop-casting CsPbBr3 NCs onto paper strips that are pre-soaked in chloride solutions. A considerable blue shift in fluorimetry proves them to be an excellent sensing medium as practical spectrochemical probes for on-site detection of chlorides. Based on this, a colour chart and selectivity chart to access the presence of chlorides and their concentration is also demonstrated.
An interactive session between Prof U Ramamurty, President Chair Professor, School of Mechanical & Aerospace Engineering at Nanyang Technological University (NTU), Singapore, and the faculty members of SRM University – AP, Andhra-Pradesh was held on Monday.
During the discussion, Prof Ramamurty emphasized the importance of research collaboration between faculty members from different research areas and about utilizing expertise to achieve significant scientific output.
Dr Pardhasaradhi Maram from the Department of Chemistry, Dr Sabyasachi Mukhopadhyay from the Department of Physics, and Prof G S Vinod Kumar from the Department of Mechanical Engineering presented their detailed research areas that focus on storage devices, catalysts for value-added products, energy and sensing devices, novel metallic materials, additive manufacturing of metals and Bio-implants, and industry collaborative research work.
Prof Ramamurty said that he is glad to see that productive science is being done at SRM University-AP. “Given that the University has started only 4 years ago and been functioning amidst a pandemic for more than one and a half years, the progress in research is significant and very impressive. Interdisciplinary efforts between various departments in the University will give effective results”, he added.
Prof D Narayana Rao, Pro-Vice-Chancellor, SRM University – AP expressed his interest in establishing NTU – SRM joint Centre for Advanced Research in functional and structural materials at SRM University campus to Prof Ramamurty.

A research paper titled “Nitrogen doping derived bridging of Graphene and Carbon Nanotube composite for oxygen electroreduction” has been published by Prof Ranjit Thapa, Professor of Physics, SRM University – AP, as a co-author, in International Journal of Energy Research, having Impact Factor of 5.164.
In this work, the research group investigated the origin of high catalytic activity of oxidic-N configuration in nitrogen-doped CNT and graphene heterostructure using density functional theory (DFT). We have plotted the free energy profile of the oxygen reduction reaction (ORR) to estimate the thermodynamic overpotential and catalytic performance of the respective active sites. The overpotential is related to the quantifying parameter ∆GOH (with R2 = 0.98) and the π electron density at the Fermi level, defined as an electronic descriptor, which is highly correlated with the ∆GOH with R2 value 0.96. For various N doped configurations, we correlated the ∆GOH values with π electron density at the Fermi level and found that the carbon site adjacent to the oxide-N configuration is a more prominent site for ORR. Further, we show that the oxidic-N configuration in the heterostructure of graphene and CNT is the ideal configuration, which gives a lower overpotential of 0.54 eV for ORR on adjacent carbon sites. Therefore, the charge transfer occurs from underneath CNT to graphene and increases the value of π electron density at the Fermi level which leads to the higher catalytic performance of the active site.
In the early 20th century, fuel cells were invented and their global impact has not reached up to its regular commercialization when compared with battery technology. The fuel cell device could be a powerful technique to generate electricity for large energy demand without greenhouse gas emissions. However, other major hurdles in the commercialization of fuel cell devices are the cost of platinum (as a catalyst), its poisoning and stability. Recently, carbon-based materials such as graphene, carbon nanotubes and activated carbon have been evolved as metal-free low-cost catalysts due to their (i) high abundance/yield (ii) reactivity towards oxygen just by introducing impurities like heteroatoms or other metals. However, identifying an efficient design principle to search optimal doping configurations in various carbon systems is a grand challenge for researchers.
This work is done in collaboration with Research Institute, SRM Institute of Science & Technology, Kattankulathur-603203, Chennai (India).
In future, the study aims to propose the effective design principle for various doped carbon systems as a catalyst to identify the optimal active sites and configurations for ORR. The role of π orbital in carbon systems such as graphene, graphene nanoribbons, carbon nanotube, etc is very important and can be a general electronic descriptor to define catalytic activity. Also, π electron descriptors and machine learning algorithms based combined approach can boost the search for ideal carbon catalyst for ORR with low DFT cost.
