For example, the JPEG format of 1992 can perform as well as many modern formats given newer techniques exploited in mozjpeg and ISO libjpeg, yet they would be lumped together with the legacy encoders in such a scheme. [2] The image compression community has long used objective quality metrics like SSIM to measure the effects of compression.
Typically, compressions using lossless operation mode can achieve around 2:1 compression ratio for color images. [5] This mode is quite popular in the medical imaging field, and defined as an option in DNG standard, but otherwise it is not very widely used because of complexity of doing arithmetics on 10, 12, or 14bpp values on typical embedded 32-bit processor and a little resulting gain in ...

JPEG XL is a royalty-free open standard for the compressed representation of raster graphics images. It defines a graphics file format and the abstract device for coding JPEG XL bitstreams.
Again, "libjpeg-turbo" is not libjpeg! "libjpeg-turbo" is an incompatible, illegal, and erroneous fake variant of the original libjpeg. The original libjpeg is released by the Independent JPEG Group, which is now at version 9.1, and that is the title and subject of this article. Guido Vollbeding 16:20, 10 August 2014 (UTC)
