     Sponsored Projects


1. (Principal Investigator) Segmentation of MR Medical Imaging Data for Diagnostics . Sponsored by U.P. Council of Science and Technology, 1999 - 2000. This project aimed at fur developing the computerised segmentation techniques to used by MR radiologists in a real-life hospital setting. Several fast and accurate algorithms for image segmentation were developed.

2. (Principal Investigator) Development of Digital Signal Processing Laboratory. Sponsored by the union Ministry for Human Resource Development, 1992 to 1994. A high speed signal processing laboratory based on state of the art computer interfaced ADSP systems was developed for graduate studies and research work in the ACES at IIT Kanpur. Subsequently Texas Instruments supported further upgradation of this lab using TI-TMS platforms. The lab is now extensively used for advanced work in signal processing.

3. (Co-investigator) Computer Vision. Sponsored by the All India Council for Technical Education, 1995 -1998. This project developed computer vision algorithms which were subsequently implemented on high speed reconfigurable multiprocessor based vision systems.

4. (Co-investigator) Low bit Rate Video Compression. Sponsored by Silicon Automation Systems, 1997 - 99. The project supported hardware development in Signal Processing and student fellowships for development work. Algorithm development has been the main focus of this project.
