remote sensing, surveillance and monitoring, and military. Image Object Tracking and Segmentation Using Active Contours A method of segmentation of video images involving identification of object contours and segmenting contours using an estimation of weighted length of contour segments. Device and Method for Automatically recreating a Content Preserving and Compression Efficient Lecture Video A video lesson, which involves merging of video and audio data captured by several fixed cameras placed in the lecture room, requires intense manual labor for converting it into a video lecture. Chaudhuri's method provides recreation of a lecture by automatic merging of the video and audio content by preserving content and compression efficiency. The system eliminates redundant and unstructured data streams. System for creating a capsule representation of an instructional video This method involves generation of a compressed video capsule of a lecture by recognizing activities and segmenting them based on the parameters of talking head, writing hand and slideshow using Hidden Markov model. The process separates the content frames of writing hand and slideshow from the non-content frames of talking head and a capsule is generated by selecting suitable content and non-content frames. System and method for fusing images The method involves identification and segregation of images into plurality of sets and fusing the sets into a fused image. Several such fused images are fused again to generate the desired fused image. Awards and honors Chaudhuri received the Shri Hari Om Ashram Prerit Vikram Sarabhai Research Award of the Physical Research Laboratory in 2011, followed by the Prof. S. V. C. Aiya Memorial Award of the Institution of Electronics and Telecommunication Engineers, the same year. The Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 2004. The Prof. H.H. Mathur Excellence in Research Award of the Indian Institute of Technology, Bombay reached him in 2007 and he received the G. D. Birla Award for Scientific Research from the K. K. Birla Foundation in 2010. A year later, he was awarded the 2011 NASI-Reliance Industries Platinum Jubilee Award. Chaudhuri has received three major research fellowships in his career; starting with Swarnajayanti Fellowship of the Department of Science and Technology in 2003, followed by the Alexander von Humboldt fellowship in 2007 and J. C. Bose National Fellowship of the Science and Engineering Research Board (SERB) in 2008. The year 2003 brought him two more honors
