Abstract
The image is broken down into a breakdown color space. For each broken down source pixel, if a source point Pis used to represent the end of the color source vector OPassociated with said source pixel, component points P, P, . . . , P, . . . , Pare used to represent the ends of the color component vectors OP, OP, . . . , OP, . . . , OPassociated with the component pixels, if a limit sphere of radius Lis defined, centered on the point P, then said breakdown is such that the following applies: PP, PP, PP, . . . , PP≧K×L, with K≧0.5. The effectiveness of the scrambling is then significantly enhanced.
