To keep abreast of the fast paced developments in the computing field, The Department maintains a highly qualified Faculty conducting research in broad computing themes, and offers opportunities for postgraduate research leading to a PhD in Computer Science. The Faculty has research expertise in major areas of Computer Science, and invites interest from highly motivated and well-qualified graduates to work towards a doctorate. Though Computer Science and its application across all the sciences is currently revolutionising a wide range of human activities, it itself is undergoing revolutionary change. The Department positions itself to anticipate and drive these developments in all major areas including, Image Processing, Computer Vision, Software Engineering, Machine Learning, Data Mining, Natural Language Processing (NLP), Speech Processing & Recognition and Network & Information Security. Thus far, the department has successfully produced three PhDs, and presently some of its faculty members are on study leave pursuing PhD, both abroad as well as locally. This will further strengthen its research capacity. The department endeavours to attain high standards of research, and is actively contributing in national and international journals and conferences
The Department provides computing and Internet support for all academic and research staff and students.The computer labs are well-equipped comprising 170 workstations of various contemporary models and supporting equipment. Several important software tools used in research relating to speech processing, video processing and data mining are available. The Department has access to a large numbers of licensed software from major software companies. The department also facilitates Faculty and research students to utilize library collection which includes general circulation books, reference books, encyclopedias, handbooks, periodicals, research journals, government and archive documents, microfilms, microfiches, audio / video cassettes, CD-ROM databases and software. Online Journals includingIEEE, ACM, Journal of Acoustic Society of America, Elsevier Science Direct, Springer Link can be accessed through digital library facility. The library offers specialized services in the Campus utilizing computerized retrieval of bibliographic databases containing references to thousands of articles, books, proceedings, technical reports and statistics.
Computer Vision & Image Processing
Research in this area includes modelling object behaviour, human facial and body action, facial synthesis and super resolution, multi-modal biometrics, 3D deformable shape, and structure from motion. The work has been widely applied to vehicle and people detection and tracking; behaviour screening and anomaly detection in public space CCTV.
The research is directed towards techniques, methods and processes for development of large complex software intensive systems. Current areas of research include Requirements Engineering, Verification & Validation, Software Process Quality, System Safety, and Software Management. The research results may be applied to a variety of application areas ranging from small- embedded systems to large software applications.
Natural Language Processing
This research area focuses on algorithms that allow computers to process and analyze human languages. This research area ranges from basic research in computational linguistics to key applications in human language technology, which covers areas such as semantics, tagging, information extraction and named entity recognition. This will involve data analysis with innovative rule-based, probabilistic and machine learning approaches to NLP.
Machine learning is the study of adaptive computational systems that improve their performance with experience. Research in this area focuses primarily on natural language learning, statistical relational learning, transfer learning, and active learning, particularly with application in speech and computer vision domains.
Data mining research focuses on the development of new algorithms, many of which are based on optimization approaches, but also on the development of new tools and applications. The research includes work on semi-structured data and text, as well as stream data. Data mining application in Education and Health domain is under research.
Network & Information Security
Research in this area includes computer security, cryptography and network security. Some of the key research themes are Anonymity, Authenticity, Availability, Digital Rights Management, Identity Management, Information Hiding, Privacy, Cryptanalysis, Computer Security: defenses against malware Reliability, Human Aspects of Security, Watermarking, Steganography and Steganalysis. It also includes quantum cryptography (or Quantum Key Distribution), which is a new trend in information security.
Speech Processing and Recognition
Research in this area is being conducted on developing methods for robust speech recognition, speaker verification and applications of speech processing using machine learning techniques.
