This repository embed the message into an Image using optimized DWT-DCT

Fast Algorithm for the 3-D DCT and its video compression application

Robustness of DWT vs DCT is graded based on the quality of extracted watermark. The measure used is the Correlation coefficient (0-100%).

ImageFusion algorithm, SSIM and PSNR evaluation（常见图像融合算法以及SSIM和PSNR评价

A technique for embedding one mark or image within another using Entropy as a discriminant to identify the most strategic points of the image, DCT and DWT transforms are also used for insertion, the method is designed to be robust against jpeg compressions.
