As a measure of accuracy of the color signal reconstruction, we use the CIELUV unit of distance DeltaE in uniform color space [29] Since a color signal is already an illumination 6 Buchsbaum [4] uses a Karhunen Lo eve expansion as well, but diagonalizes in an RGB space, not with respect to the components of the color signal. See also [21] 7 The (cumulative) variance accounted for by the first five vectors is: 0.95819, 0.99063, 0.99724, 0.99839, 0.99893. 14 Mark S. Drew and Brian V. ....

Color Opponency Constitutes A Sparse Representation For.. - Lee, Wachtler, Sejnowski (2001) (1 citation) (Correct)
....the ICA results support the argument that basis functions for efficient coding of chromatic natural images are non orthogonal. In order to determine whether the color opponency is merely a result of correlation in the receptor signals due to the strong overlap of the photoreceptor sensitivities [15], we repeated the analysis, this time assuming hypothetical receptor sensitivities which do not overlap, but sample roughly in the same regions as the L , M , and S cones. We used rectangular sensitivities with absorptions between 420 and 480 nm ( S ) 490 and 550 nm ( M ) and 560 and 620 nm ....

....threshold has a value of unity. Apparently, thresholds in the color direction are closer to the origin and are therefore lower. It can be seen that our images contain large variations along the luminance axis, but the average contrast in the color direction is lower by a factor of about 20 25 [15,16]. The advantage of the color system over the luminance system, because of its increased sensitivity, is far outweighed by the reduction in the naturally occurring color contrasts. Figure 3b also shows the results of spectroradiometric measurements of highly saturated fruit and vegetable objects ....

Analysis of color images have mostly focused on coding efficiency with respect to the postreceptoral signals [4, 12]. Buchsbaum et al. 4] found opponent coding to be the most efficient way to encode human photoreceptor signals. In an analysis of spectra of natural scenes using PCA, Ruderman et al. 12] found principal components close to those of Buchsbaum. While cone opponency may give an optimal code for ....
