Klein,Amnon D. Silverstein and Thom Carney. In Human Vision, VisualProcessing and Digital Display III, 1992.for 1 minute per pixel viewing.Specifying only one table in this xml file has two effects when used withthe ImageMagick option-define jpeg:q-table=PATH/TO/THIS/FILE1) 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>
