Algorithm 4

Computation of dissimilarity distance of two colors.

	Procedure: DISSIMILARITY_DISTANCE_OF_TWO_COLORS
	Input:
	: first HSV color
	: second HSV color
	Output:
	: color dissimilarity distance of two HSV colors
	Goal:
	Compute dissimilarity of two colors
	BEGIN
	//Grey color with small V, S, or unidentified H
	isGrey1 =
	isGrey1 =
	//Check if both are grey color
	if (isGrey1 && isGrey2):
	if (isGrey1 = = 0 && isGrey2 = = 0):  //both are color
	else: #do not care about H channel
	END
