Introduction

CLIC 2022, the 5th Workshop and Challenge on Learned Image Compression, aims to gather publications which will advance the field of image and video compression using machine learning and computer vision. We want to encourage the development of novel encoder/decoder architectures, novel ways to control information flow between the encoder and the decoder, new perceptual losses, and new ways to learn quantized representations.

At the workshop we will also present the winners of our annual compression challenge. Like the workshop, the challenge is designed to encourage the development of new learned codecs. But it is also an opportunity to evaluate and compare end-to-end trained approaches against classical approaches and every submission is welcome.

Location

The workshop will be part of CVPR 2022 which will be held in New Orleans, Louisiana. The conference will take place between June 19 and June 24 and the online workshop will be held on June 19, 2022.
