| Title | <p>ISO/IEC 15444-5:2003 provides two independently created software reference implementations of ISO/IEC 15444-1, in order to assist implementers of ISO/IEC 15444-1 in testing and understanding its content. ISO/IEC 15444-1 defines a set of lossless and lossy compression methods for coding continuous-tone, bi-level, greyscale or colour digital still images.</p> <p>The reference software is informative only. ISO/IEC 15444-5:2003 does not define any additional part of the JPEG 2000 image coding system.</p> <p>Each version of the reference software contains source code, which may be compiled to provide the following functionality: </p> <ul><li>transcoding from selected, widely available image formats into a JPEG 2000 codestream; </li><li>transcoding from selected, widely available image formats into the JP2 file format;</li><li>selection of a wide range of JPEG 2000 encoding options (as documented in each reference software);</li><li>decoding from a JPEG 2000 codestream to a range of selected widely available image formats;</li><li>partial processing of a JP2 file to extract a JPEG 2000 codestream for decoding to a range of selected widely available image formats (Note that the reference software does not implement a conforming JP2 file reader.);</li><li>some additional tools to help with evaluation and testing.</li></ul> |
