ABSTRACT:
A method Abstract a histogram of HSV (Hue-Saturation-Value) colors from a color signal. The method includes receiving the color signal having a luminance component (Y) and chrominance components (CbCr). One section of a lookup table is selected according to the luminance component (Y) of the received color signal. The lookup table is divided into a plurality of sections each storing quantizing index values. Each section is divided by concentric circles corresponding to quantizing boundaries of the Saturation from a center, and divided by radial lines. Corresponding quantizing index values are selected according to the chrominance components (CbCr) of the received color signal in the selected section. The histogram index of the HSV colors is abstracted with reference to the selected section and the quantizing index values selected in the selected section.
