IMAGE PROCESSING METHOD FOR INCREASING THE BLURRING OF PIRATED IMAGES

摘要

An image is broken down in a colour breakdown space. For each broken down source pixel (E_S0j), if a source point P_S0j is used to represent the end of the colour source vector OP_S0j associated with said source pixel (E_S0j), component points P_1j, P_2j, ..., P_kj , P_nj are used to represent the ends of the colour component vectors OP_1j, OP_2j, ..., OP_kj, ..., OP_nj associated with component pixels (E_Clj, E_C2j, ..., E_Ckj, ..., E_Cnj), and if a boundary sphere having radius L_S0j and centred on point P_S0j is defined, then said breakdown is such that P_S0P_j1, P_S0P_j2, P_S0P_jk. , P_S0P_jn = K_S0j x L_S0j, where K_S0j > 0,5. The blurring effectiveness is thus substantially enhanced.
