Human re-identification, i. e., human identification across cameras without an overlapping view, has important applications in video surveillance. The problem is very challenging due to color and illumination variations among cameras as well as the pose variations of people. Assuming that the color of human clothing does not change quickly, previous work relied on color histogram matching of cl...

An efficient technique is presented for obtaining dense stereo correspondence using a new adaptive Block Matching technique. First, one of the color stereo images (e.g., the left) is segmented into chromatic and achromatic regions using perceptual attributes in the HSI color space. Then the Block Matching technique is applied to the stereo images using adaptive similarity measures. The results ...

A patient from a large kindred with adrenoleukodystrophy showed profound disturbance of color ordering, color matching, increment thresholds, and luminosity. Except for color matching, his performance was similar to blue-cone "monochromacy," an X chromosome-linked recessive retinal dystrophy in which color vision is dichromatic, mediated by the visual pigments of rods and short-wave-sensitive c...

Various recent studies have shown that observer variability can be a significant issue in modern display colorimetry, since narrow-band primaries are often used to achieve wider color gamuts. As far as industrial applications are concerned, past works on various aspects of observer variability and metamerism have mostly focused on cross-media color matching, an application context that is diffe...
