Scope 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 / ISO/IEC 1091 8-1 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.
