Abstract Color assessment of animal source foods was investigated using a computer vision system (CVS) and traditional colorimeter. With the same measurement conditions, color readings varied between these two approaches. The measured by CVS highly similar to actual foods, ranged from 75.0%-100.0% colors, whereas colors read Minolta colorimeter showed non-typical appearances. CVS-obtained were ...

In this paper, we propose a color to grayscale image conversion algorithm (C2G) that aims to preserve the perceptual properties of the color image as much as possible. To this end, we propose measures for two perceptual properties based on contemporary research in vision science: brightness and multi-scale contrast. The brightness measurement is based on the idea that the brightness of a graysc...
