Member Data Documentation

unsigned char ColorTableTSL::colorClasses[32][64][64]

The color table. Each entry contains both the color class A (lower 4 bits) and the color class B (higher 4 bits) values. As Y information is less relevant, only 5 bits are used for Y; U and V use 6 bits. Definition at line 132 of file ColorTableTSL.h.

unsigned char ColorTableTSL::tsl_threshold[numOfColors][2][3]

The TSL threshold table. This table stores the TSL thresholds as given by addColorClass() and updateColorClass(). The first index selects the color class. The second index selects min (0) or max (1). The third index selects t (0), s (1) or l (2). Definition at line 142 of file ColorTableTSL.h. Referenced by addColorClass(), classifyTSL(), clear(), operator<<(), and operator>>().

unsigned char ColorTableTSL::tsl_index

The TSL threshold index. Definition at line 147 of file ColorTableTSL.h. Referenced by addColorClass(), classifyTSL(), and clear().

colorClass ColorTableTSL::tsl_order[numOfColors]

The TSL order table. It contains a permutation of colorClass. Definition at line 153 of file ColorTableTSL.h. Referenced by addColorClass(), classifyTSL(), clear(), operator<<(), and operator>>().
