Perceptual quality assessment of JPEG, JPEG 2000, and JPEG XR
SPIE Proceedings, 2010In this paper, we examine the rate-distortion performance in terms of perceptual quality of JPEG XR (ISO/IEC 29199-2 | ITU-T Rec. T.832)1 and earlier standardized image compression algorithms such as JPEG (ISO/IEC 10918-1 | ITU-T Rec. T.81)2 and JPEG 2000 (ISO/IEC 15444-1 | ITU-T Rec. T.800)3.

JPEG Column: 96th JPEG Meeting
ACM SIGMultimedia Records, 2022The 96 th JPEG meeting was held online from 25 to 29 July 2022. The meeting was one of the most productive in the recent history of JPEG with the analysis of the responses of two Calls for Proposals (CfP) for machine learning-based coding solutions, notably JPEG AI and JPEG Pleno Point Cloud Coding.

International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II, 2005
In this paper, a simple approach is proposed to improve the performance of JPEG. In the proposed approach, the coding scheme is identical to the JPEG except only a fixed number of coefficients are coded for each image block. Consequently, it is totally compatible with the JPEG and is termed as zonal JPEG.

JPEG Column: 99th JPEG Meeting
ACM SIGMultimedia Records, 2023The 99th JPEG meeting was held online, from 24th to 28th April 2023. Providing tools suitable for establishing provenance, authenticity and ownership of multimedia content is one of the most difficult challenges faced nowadays, considering the technological models that allow effective multimedia data manipulation and generation.

Denoising JPEG images by re-application of JPEG
1998 IEEE Second Workshop on Multimedia Signal Processing (Cat. No.98EX175), 2002A novel method is proposed for post-processing of JPEG-encoded images, in order to reduce coding artifacts and enhance visual quality. Our method simply re-applies JPEG to the shifted versions of the already-compressed image, and forms an average. This approach, despite its simplicity, offers better performance than other known methods, including those
