JPEG Column: 106th JPEG Meeting

ACM SIGMultimedia Records
The 106th JPEG meeting was held online from January 6 to 10, 2025. During this meeting, the first image coding standard based on machine learning technology, JPEG AI, was sent for publication as an International Standard. This is a major achievement as it leverages JPEG with major trends in imaging technologies and provides an efficient standardized ...

Why JPEG is not JPEG — Testing a 25 years old Standard

2018 Picture Coding Symposium (PCS), 2018
While ISO WG1 recently celebrated the 25th anniversary of its most successful standard, it seems to be more than surprising that up to now, no reference implementation of this standard exists. During an ongoing activity aiming at filling this gap, several observations have been made in how far the “living standard” deviates from the ISO documents.

Optimal JPEG decoding

Proceedings 1998 International Conference on Image Processing. ICIP98 (Cat. No.98CB36269), 2002
This paper introduces an optimal decoding scheme for the baseline Joint Photographers Expert Group (JPEG) standard. In particular, it deals with the minimization of a half-quadratic criterion which takes into account observed data, a priori knowledge of the solution, and precise spatial location of blocking artifacts.

Visual comparison of JPEG 2000 versus conventional JPEG

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
One difficulty in image compression research is designing meaningful performance metrics. Purely numerical measures such as PSNR are unsatisfactory because they do not correlate well with human assessment. We introduce a method of subjective image evaluation for image compression called calibrated rank ordering (CRO).
