Abstract
An apparatus includes a memory and a circuit. The memory may be configured to store an input image having a plurality of color channels. The circuit may be configured to (i) calculate a plurality of average values of each of the color channels in a plurality of windows around each of a plurality of pixel locations in the input image, (ii) calculate a plurality of feature values based on the average values using a feature extraction process and (iii) generate a plurality of likelihood values of a specific color at each of the pixel locations using the feature values in a color classification process.
