- Authors: Benoit Brummer, Christophe De Vleeschouwer
- Abstract summary: Constant market requirements for a low-complexity image have led to the recent development and standardization of a lightweight image named JPEG XS.
In this work we show that JPEG XS compression can be adapted to a given task and content, such as preserving visual quality on desktop content or maintaining high accuracy in neural network segmentation tasks.

- Abstract: Most current research in the domain of image compression focuses solely on
achieving state of the art compression ratio, but that is not always usable in
today's workflow due to the constraints on computing resources.
Constant market requirements for a low-complexity image codec have led to the
recent development and standardization of a lightweight image codec named JPEG
XS.
In this work we show that JPEG XS compression can be adapted to a specific
given task and content, such as preserving visual quality on desktop content or
maintaining high accuracy in neural network segmentation tasks, by optimizing
its gain and priority parameters using the covariance matrix adaptation
evolution strategy.

This work introduces Semantically Masked VQ-GAN (SQ-GAN), a novel approach to optimize image compression for semantic/task-oriented communications.
SQ-GAN employs off-the-shelf semantic semantic segmentation and a new semantic-conditioned adaptive mask module (SAMM) to selectively encode semantically significant features of the images.

This paper is concerned with learning-based compression schemes whose compressed-domain representations can be utilized to perform visual processing and computer vision tasks directly in the compressed domain.
We adopt the learning-based JPEG-AI framework for performing material and texture recognition using the compressed-domain latent representation at varing bit-rates.
It is also shown that the compressed-domain classification can yield a competitive performance in terms of Top-1 and Top-5 accuracy while using a smaller reduced-complexity classification model.
