DLP : Advances in Image/Video Compression Using Graph Transform | 16 May 2016


Title :  Advances in Image/Video Compression Using Graph Transform
Date :  16 May 2016 (Monday)
Time :  10:00am – 12:00pm
Venue :  Dewan Taklimat, Level 2, Tower Block, Faculty of Engineering, UPM



This talk describes recent developments in several areas of image and video compression employing new signal processing and computer vision techniques. After an initial discussion about the future of video compression, the talk will be centered around graph transforms. I will first address the design of graph transforms achieving very good compression efficiency on both piecewise-smooth and natural images, and their application to image compression and intra-frame video compression. Next, I will introduce a new video compression paradigm that replaces macro blocks with superpixels, and employs a graph transform to encode each super pixel. Finally, I will describe a new and very efficient transform, called ?steerable? DCT, which is able to orient the DCT basis functions spatially and spectrally so as to adapt to directional features of the block being encoded.

Speaker: Assoc. Prof. Enrico Magli

Enrico Magli was born in Torino (Italy) in 1972. He received the degree in Electronics Engineering in 1997, and the Ph.D. degree in Communications Engineering in 2001 at Politecnico di Torino. From January 2011 he holds an Associate Professor position in the Dept. of Electronics of the same University. His research activities are in the field of compressed sensing, error resilient image and video coding, compression of remote sensing images, distributed source coding, and image/video security. He has coauthored over 130 scientific papers in international journals and conferences, including more than 50 journal papers, and has organized several journal special issues and conference special sessions.
