Summary:

To simplify the use of the JPEG format (Rec. ITU-T T.81 | ISO/IEC 10918-1), this Recommendation | International Standard provides two reference software implementations that provide guidance how to implement Rec. ITU-T T.81 | ISO/IEC 10918-1. Rec. ITU-T T.81 | ISO/IEC 10918-1 is in wide use worldwide. It provides a compressed representation of continuous tone digital images. This Recommendation was developed jointly with ISO/IEC JTC 1/SC 29/WG 1 (JPEG), and corresponds as common text with ISO/IEC 10918-7. This third edition cancels and replaces the second edition, which has been technically revised. The main changes compared to the previous edition are as follows: This second edition updates Reference Software A to release 1.65, and Reference Software B to release 3.0.0. This version of Reference Software A corrects implementation errors and improves the overall stability of the software. This version of Reference Software B now also includes support for 8-bit and 12-bit codestreams in one single integrated code.
