This repository embed the message into an Image using optimized DWT-DCT
Robustness of DWT vs DCT is graded based on the quality of extracted watermark. The measure used is the Correlation coefficient (0-100%).
Steganography using Huffmann Coding and 2d - Block DCT
MATLAB Toolbox for digital signal processing using Weyl-Heisenberg bases.
Fast Algorithm for the 3-D DCT and its video compression application
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.
