Detailed Description

Create a chromaticity histrogram feature vector.

Due to the fact that chromaticity has no information contents on intensity, this feature is highly illumination invariant. The 2D chromaticity-histogram is a triangular matrix and will be coded in the 1D feature vector to save memory space.
