Co-occurrence matrix Let a texture f be given (of size 5x5 with 3 intensity levels). Calculate the gray-level coocurrence matrix (GLCM) G(1,1) (i.e. distance one in vertical direction for this texture. Normalize it and calculate the energy and contrast features (c and c2) for this matrix. TO 2 2 0 2 2 1 0 0 1 f = 1 1 1 2 2 0 1 0 0 2 2 0 2 1 2
