Abstract |
|
Now a days the copy right protection is an important use of several image processing techniques. In order to protect our image, different image hiding techniques like steganography, cryptography are used in olden days. The watermarking technology used in the year 1826 besides of steganography and cryptography. Actually a watermarking technique involves an image hiding process. We proposed a new method of hiding information image into cover image in this paper. In our proposed method the cover image (original image) goes under bit plane slicing, the hidden image goes under a filter operation to detect the edges. Finally these two images are embedded and forms a new watermarked image. Our experimental results prove that the proposed watermarking method has low MSE & high PSNR values when compared with the other watermarking algorithms like DCT and DWT. |
