Abstract:
The image is broken down into a breakdown color space. For each broken down source pixel, if a source point PS0j is used to represent the end of the color source vector OPS0j associated with said source pixel, component points P1j, P2j, . . . , Pkj, . . . , Pnj are used to represent the ends of the color component vectors OP1j, OP2j, . . . , OPkj, . . . , OPnj associated with the component pixels, if a limit sphere of radius LS0j is defined, centered on the point PS0j, then said breakdown is such that the following applies: PS0Pj1, PS0Pj2, PS0Pjk, . . . , PS0Pjn≧KS0j×LS0j, with KS0j≧0.5. The effectiveness of the scrambling is then significantly enhanced.
