"WebbGenerally, colour segmentation, just as the greyscale one, may be based on the analysis of 3D colour histograms or their more convenient 2D projections. A colour histogram is built by partitioning of the colour space onto a fixed number of bins such that the colours within each bin are considered as the same colour. " - Histogram segmentation
