This Recommendation | International Standard is concerned with compliance tests for the continuous-tone still image encoding processes, decoding processes, and compressed data formats specified in ITU-T Rec. T.81 ISO/IEC 10918-1.
This Specification:
- specifies compliance tests for the ITU-T Rec. T.81 | ISO/IEC 10918-1 compressed data formats;
- specifies compliance tests for the ITU-T Rec. T.81 1 ISO/IEC 10918-1 encoding processes;
- specifies compliance tests for the ITU-T Rec. T.81 | ISO/IEC 10918-1 decoding processes;
- specifies a method for constructing application-specific compliance tests;
- gives guidance and examples on how to implement these tests in practice.
This Specification specifies normative generic compliance tests for the ITU-T Rec. T.81 | ISO/IEC 10918-1 encoding and decoding processes. These compliance tests are applicable to "stand-alone" generic implementations of one or more of the encoding and decoding processes specified in ITU-T Rec. T.81 | ISO/IEC 10918-1. Among the purposes of these tests is to ensure that generic encoder (and decoder) implementations compute the discrete cosine transform (DCT) and quantization functions with sufficient accuracy.
