Combining DWT/KLT for Secure Transfer of Color Images

The idea of the proposed work is to contribute to the secure transfer, medical color images, through the proposal of a digital watermarking scheme. The idea of this approach is to contribute in the medical domain. The watermark to be inserted is the diagnosis own to patient's. The tested images are the medical endoscopic images. The principal idea turns on ameliorate of the principal constraints constituted in all watermarked system such as the imperceptibility and the robustness of the watermarking system. Experimental results show that the proposed scheme is robust against most common attacks including JPEG 2000 compression, low-pass filter, rotation and Salt & Pepper noise.
