Workshop and Challenge on Learned Image Compression (CLIC)


Our workshop aims to gather publications which will advance the field of image compression with and without neural networks. Even with the long history of signal-processing oriented compression, taking new approaches to image processing have great potential, due to the proliferation of high-resolution cell-phone images and special hardware (e.g., GPUs). The potential in this area has already been demonstrated using recurrent neural networks, convolutional neural networks, and adversarial learning, many of these matching the best image-compression standards when measured on perceptual metrics. As such, we are interested in the various techniques associated with this class of methods. Broadly speaking, we would like to encourage the development of novel encoder/decoder architectures, novel ways to control information flow between the encoder and the decoder, and learn how to quantize (or learn to quantize) better.

Ramin Zabih


Ramin Zabih is a research scientist at Google, on leave from his position as a professor of Computer Science at Cornell Tech in NYC. His research focuses on computer vision, primarily the development and application of discrete optimization techniques. He served as a program chair for the biggest vision conference (CVPR) in 2007, as a general chair for CVPR in 2013; in addition, he will be a general chair for CVPR again in 2020, and for the main European vision conference (ECCV) in 2018. He served as editor in chief of the IEEE Transactions on Pattern Analysis and Machine Intelligence from 2009-2012, and chaired the PAMI-TC from 2013-2015. He received a best paper award at ECCV 2002, and test of time awards at ECCV 2012 and ICCV 2013. In 2016 he was awarded the PAMI Mark Everingham prize for his service as founder and president of the Computer Vision Foundation (CVF). He is a fellow of the ACM and the IEEE.Read More

Jens Ohm

RWTH Aachen

Jens-Rainer Ohm holds the chair position of the Institute of Communication Engineering at RWTH Aachen University, Germany since 2000. His research and teaching activities cover the areas of motion-compensated and 3-D image/video processing and analysis, multimedia signal compression, transmission and content descr iption, audio signal analysis, as well as fundamental topics of signal processing and digital communication systems. Since 1998, he participates in the work of the Moving Picture Experts Group (MPEG). He has been chairing/co-chairing various standardization activities in video coding, namely the MPEG Video Subgroup since 2002, the Joint Video Team (JVT) of MPEG and ITU-T SG 16 VCEG from 2005 to 2009, and currently, the Joint Collaborative Team on Video Coding (JCT-VC), as well as the Joint Video Exploration Team (JVET). Prof. Ohm has authored textbooks on multimedia signal processing, analysis and coding, on communication engineering and signal transmission, as well as numerous papers in the fields mentioned above.Read More
