Watermarking on images using Discrete Cosine Transform and Haar Transform

Demo of Digital Watermarking in images

The program implements forward and inverse version of 2D Discrete Fourier Transform (FFT), Discrete Cosine Transform, Discrete Walsh-Hadamard Transform and Discrete Wavelets Transform (lifting scheme) in C/C++. The output of transforms is displayed for a given input image.

The Wearables Data Compression Toolbox is designed to share data compression algorithms that have been evaluated on wearables data.
