Secret-Fragment-Visible Mosaic Image-Creation and Recovery via Colour Transformation
R P Remya, M. Harikrishnan · IJSRD : international journal for scientific research and development · 2015
Secret-fragment-visible mosaic image which automatically transforms the secret image into a meaningful mosaic image of the same size. The mosaic image looks like to an arbitrarily selected target image. It may be used as a camouflage of the secret image and yielded by dividing the secret image into fragments and transforming their color characteristics to the corresponding blocks of the target image. Some technologies are designed to conduct the color transformation process so that the secret image may be recovered. The information required for recovering the secret is embedding into the created mosaic image. Good experimental results are showing the feasibility of the proposed method.
