public class AlgorithmColorSaturation extends AlgorithmBase
This algorithm changes the saturation of a color image while keeping the hue and intensity constant. Intensity = (R + G + B)/3 Hue = theta if B G with theta = arccos{0.5[(R - G) + (R - B)]/sqrt[(R - G)**2 + (R - B)*(G - B)]} Saturation = 1 - 3 * min(R, G, B)/(R + G + B) Derived from quaternion formula: Radial dilation = ((a + 2)/2)*(r*i + g*j + b*k) + (a/2)*u*(ri + g*j + b*k)*u where u is a pure unit quaternion. For radial dilation around the gray line where r = g = b, set u = (i + j + k)/sqrt(3) Radial dilation around gray line = ((a + 2)/2)*(r*i + g*j + b*k) + (a/2)*((i + j + k)/sqrt(3))*(r*i + g*j + b*k)*((i + j + k)/sqrt(3)) which expands space outward for a > 0 or moves it out from the r = g = b line and compresses space for a-
