Abstract:
Non-adjacent rows (i) in the visibility matrix (Msr) that have a large number of common elements are automatically detected (E7) and any such detected rows are permutated to put the lines detected as having a large number of common elements into sequence to form a modified visibility matrix (M′sr), and digital image coding is applied (E8) to the Boolean elements of the modified visibility matrix (M′sr).
