2019-9-1 · A histogram provides a graphical representation of the distribution of colors in an image. In other words, it produces a discretization of the colors in the image into a number of bins (fixed list of color ranges), and determines the number of image pixels in each bin. In this work, the RGB histograms for each superpixel are computed.
