F = VL_LBP(IM, CELLSIZE) computes the Local Binary Pattern (LBP) features for image I.
IM is divided in cells of size CELLSIZE. F is a three-dimensional array containing one histograms of quantized LBP features per cell. The witdh of F is FLOOR(WIDTH/CELLSIZE), where WIDTH is the width of the image. The same for the height. The third dimension is 58.
