A perception-based color space for illumination-invariant image processing. 35th annual conference on computer graphics and interactive techniques (SIGGRAPH 2008), August 11-15, Los Angeles, Calif. ACM Transactions on Graphics 27 (3): article 61, 1-7.0730-0301http://nrs.harvard.edu/urn-3:HUL.InstRepos:2640577Motivated by perceptual principles, we derive a new color space in which the associated metric approximates perceived distances and color displacements capture relationships that are robust to spectral changes in illumination. The resulting color space can be used with existing image processing algorithms with little or no change to the methods.en-USimage processingperceptioncomputer graphicscolor space10.1145/1360612.1360660
