5 Centroid Returns a 1-by-Q vector that specifies the centre of mass of the region. The first element of Centroid is the horizontal coordinate (or x-coordinate) of the centre of mass, and the second element is the vertical coordinate (or y-coordinate). 6 Entropy Entropy is a statistical measure of randomness that can be used to characterize the texture of the input image. *log2(p)) where p contains the histogram counts. 7 Maximum horizontal histogram and vertical histogram The horizontal histograms are calculated for each row and the row which has the highest value is taken as maximum horizontal histogram.
