Assistant Professor Dr Ravi Kant Kumar of the Department of Computer Science and Engineering aspires to investigate and design the most effective face recognition system appropriate enough to recognise faces in various unconstraint environments. Recently, his patent application titled A Face Recognition System (Application number: 202241030009) got published. He collaborated with his BTech student Thota Venkata Saai Praneeth, for this project. Facial recognition systems have abundant applications in Face Identification, Automobile Security, Access Control, Immigration, Education, Retail, Healthcare, Image database investigations, Surveillance, and many more.

Abstract

A facial recognition system is used for matching a human face captured in an image or a video frame with a database of faces. The system generally authenticates users by measuring facial features from the stored images. The present disclosure relates to face recognition systems. The envisaged system comprises a repository comprising a set of facial images of a plurality of subjects, a set of threshold values, and a plurality of rules. The system further comprises an image capturing unit for capturing a plurality of images of a subject’s face. A segmentation unit divides each image into a plurality of frames. The system further comprises a classifier that receives the frames and classifies frames containing faces from frames containing non-faces from the other frames. The facial features of each frame are extracted by an extractor. An analyser receives the extracted facial features and computes eigenvector values of the facial features of the frame. A comparator compares the computed eigenvector values with threshold values using the comparison rules to identify the subject.

Explanation of the research

Conventional facial recognition systems are configured to identify the contours of a person’s image captured by a camera or in real-time and compare it with the stored image to identify the person. However, external factors such as position, light conditions, camera calibration, and unconstraint conditions, among others, affect the identification of the face of the subject. Hence, comparing the faces with the help of the contours is not reliable. The present disclosure envisages a face recognition system. The system comprises a repository, an image capturing unit, a segmentation unit, a classifier, an extractor, an analyser, and a comparator. The repository consists of a set of facial images of a plurality of subjects, wherein the images define the subject’s facial features in different facial poses. Each image is tagged with an identity, a threshold integral value, and threshold eigenvector values corresponding to the facial features. The repository further comprises a first set of deep learning rules for classifying frames of a captured image into frames containing faces and frames containing non-faces, a set of extraction rules for extracting facial features from the frames 20 containing faces, the second set of deep learning rules for extracting eigenvector values of facial features of the frames containing faces. The repository additionally comprises a set of comparison rules for comparing eigenvector values of the captured facial features with the stored threshold eigenvector values to identify a subject’s face in the captured image.

Tummala Bhuvitha, Computer Science Engineering student at SRM University-AP showed exceptional talent in the 22nd state-level rifle shooting competition organised at Hyderabad Central University under the aegis of the National Rifle Association of India. She won the first position and 3 gold medals in the 10m air rifle shooting competitions held in senior, junior and youth categories, respectively.

More than 100 shooters from Andhra Pradesh took part in the competition held from the 4th to 7th of this month. Participating in the competition from SRM AP, Bhuvitha stunned the organisers by winning three gold medals in a row. Bhuvitha had won gold medals twice in the past in state and national level rifle shooting competitions held in different places. According to her father, Bhuvitha learned shooting techniques from Subrahmanyeshwar Rao, the coach at the Indian Academy of Shooting Sports in Vijayawada.

“I grew passionate about rifle shooting because it is an individual sport that requires so much concentration and focus”, says Ms Bhuvitha while sharing the joy of her success. University President Dr P Satyanarayanan, Vice-Chancellor Prof V S Rao and Registrar Dr R Premkumar praised Bhuvitha for winning three gold medals consecutively in state-level competitions.
