Computation of texture (gray level run length and gray level co-occurrence matrix based) features on a malignant mass. The conventional approach is to compute the features only on the lesion ROI (bottom-left column). We propose the computation of the features on the lesion segments dilated by three different sizes of a “disc” SE, namely 1/4 mean radial length, 1/2 mean radial length and mean radial length, and in four directions.
