IEEE CAS DLP Lecture: Advances in Image/Video Compression using Graph Transforms

IEEE CAS DLP Lecture on Advances in Image/Video Compression using Graph Transforms has been presented by Assoc. Prof. Dr. Enrico Magli from Politecnico di Torino, Italy. The lecture was held on 16 May 2016 from 10:00 a.m to 12:00 p.m in the Tower Block Meeting Room, Faculty of Engineering, Universiti Putra Malaysia. The co-organizer of this lecture are the Institute of Advanced Technology and, Department of Electrical and Electronic Engineering, UPM. Prior to the lecture, Dr. Enrico and participants enjoyed the local breakfast sponsored by IEEE CAS Malaysia Chapter.

The lecture describes technically on 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 centred on graph transforms. The presenter at first addressed 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. Then, he introduced a new video compression paradigm that replaces macro blocks with super pixels, and employs a graph transform to encode each super pixel. Finally, he described 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.

The participations from students, researchers and lectures are quite impressive with the total number of more than 40 participants. The session continued with Q&A after the presentation where the participants and speaker discussed technically on image processing techniques.

At the end of event, a group photo was taken and CASS Malaysia committee members accompanied the speaker for local lunch.
