BS ISO/IEC 10918-2:1995

This standard BS ISO/IEC 10918-2:1995 Information technology. Digital compression and coding of continuous-tone still images is classified in these ICS categories:

• 35.040.30 Coding of graphical and photographical information

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 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.

Specifies compliance tests for the ITU-T Recommendation T.81/ISO/IEC 10918-1 compressed data formats, encoding process, decoding processes and a method for constructing application-specific compliance tests.
