It is based on the one recommended in Relevance of human vision to JPEG-DCT compression by Stanley A. Klein, Amnon D. Silverstein and Thom Carney. In Human Vision, Visual Processing and Digital Display III, 1992. for 1 minute per pixel viewing. Specifying only one table in this xml file has two effects when used with the ImageMagick option -define jpeg:q-table=PATH/TO/THIS/FILE 1) This quantization table is automatically used for all three channels; 2) Only one copy is embedded in the JPG file, which saves a few bits (only worthwhile for very small thumbnails). --> <quantization-tables> <table slot="0" alias="luma"> <description>Luma Quantization Table</description> <levels width="8" height="8" divisor="1"> 16, 16, 16, 18, 25, 37, 56, 85, 16, 17, 20, 27, 34, 40, 53, 75, 16, 20, 24, 31, 43, 62, 91, 135, 18, 27, 31, 40, 53, 74, 106, 156, 25, 34, 43, 53, 69, 94, 131, 189, 37, 40, 62, 74, 94, 124, 169, 238, 56, 53, 91, 106, 131, 169, 226, 311, 85, 75, 135, 156, 189, 238, 311, 418 </levels> </table> <!-- If you want to use a different quantization table for Chroma, for example, just add: <table slot="1" alias="chroma"> <description>Chroma Quantization Table</description> INSERT 64 POSITIVE INTEGERS HERE, COMMA-SEPARATED </levels> </table> here (but outside of these comments). --> </quantization-tables>
