Histogram intersection

Swain and Ballard have proposed a method called histogram intersection to compare two color distributions. Let /// be the histogram of the input image. Let Hm be the histogram of the model object. The given histogram is compared to the histogram of the model... 

Schiele and Crowley (1996, 2000) have suggested the x2 divergence measure to compare multi-dimensional histograms. In contrast to histogram intersection, this measure does not require a sparse distribution of colors to distinguish between different objects. The Xg-divergence is calculated as... 

The final washability curve and histogram (Figure 5) are of arsenic in a sample from the Herrin (No. 6) Coal Member. The washability curve shows an intense concentration of arsenic in the heavier fractions. The curve approaches the abscissa and if extrapolated would intersect the ordinate near the origin. Arsenic is one of the least organically related elements in all four of the coals studied. 

Gamut constraint 3D Described in Section 6.4. If an empty intersection is created, the convex hulls are increased by a small amount. This process is repeated until a nonempty intersection is achieved. A histogram quantization of 256 per channel is used. (Caliblmage= )...
