dc.description.abstract | One of the most important characteristics of using fractal image coding in hiding images is the encoding process that involves very long time complexity. In this paper new hiding system is proposed that hide secret image (color or gray) into cover image (color) with reducing the time of encoding process 10 times less than classical systems that use block indexing as descriptor with fractal coding. Affine transform is used in matching process to find the closer cover block for each secret block and least significant bit method to embed the coefficient affine transform. The results indicated that the encoding time is actually reduced and hiding rate reach to 100% and the quality of extracted secret image is still within the acceptable level. | en_US |
