Image Processing in the Block DCT space

In many applications, images in the compressed domain are used for the purpose of storage and communication. Typically, DCT based JPEG compression is mostly popular in such cases. For processing such images using conventional spatial domain techniques, one would require to decompress them and apply those techniques. Further, the processed images are required to be compressed again for their storage or communication. To avoid this overhead of decompression and compression, many algorithms are being developed for computing directly in the block DCT space. In this talk, some of these algorithms outlining their design principles will be discussed. Their applications towards image resizing, filtering and transcoding will also be presented. About the Speaker:
Dr. Jayanta Mukhopadhyay (Mukherjee) has done his PhD. in the year 1990 from IIT, Kharagpur from the Dept. of Electronics and Electrical Communication Engineering in the field of Image processing. He has also done his M.Tech and B.tech from IIT, kharagpur in 1987 and 1985 respectively from the same department. His fields of interest include Image Processing, Pattern Recognition, Computer Graphics and Multimedia Systems. He served in various technical programme committees of national and international conferences. He visited University of California, Santa Barbara, USA in the summers of 2000, 2001, 2003 and 2004. He also visited the Institute for Man Machine and Communication, Technical University of Munich (TUM), Germany, for one year in 2002 as a Humboldt research fellow. He served as the head of the Computer and Informatics Center, IIT, Kharagpur from September, 2004 to July, 2007. He is a professor in the Department of Computer Science and Engineering, IIT Kharagpur. Presently, he is visiting USC under the USC-IIT Kharagpur exchange programme.Host: Prof. C-C Jay Kuo
