Color histograms unable to present spatial data;
Kobayashi’s Color Image Scale:
- 130 basic colors combined in
- 1180 three-color combinations.
The spatial correlation of combination of colors as a function of the distance between pixels.
The joint histograms, share several pixel properties beyond color.
Shigenobu Kobayashi’s system – Color Image Scale
for color semantics of single colors and three-color combinations, the Color Image Scale is well known tool used within Graphic Arts, for the selection of colors and color combinations.
spatial distance of color pixels
The spatial correlation of pairs of colors changes with distance is called a color correlogram.
An autocorrelogram captures spatial correlation between identical colors only.
