ISO/IEC 10918-7:2023
Information technology — Digital compression and coding of continuous-tone still images — Part 7: Reference software
This Specification provides reference software for the coding technology specified in Recommendation ITU-T T.81 | ISO/IEC 10918-1. While the reference implementations also provide an encoder, conformance testing of their encoding process is beyond the scope of this Specification.
