Two-Dimensional Hybrid Transform (DCT-DWT) for 2-D image watermarking
Wan Lu-chon · Microcomputer Information · 2010
First of all, this article analyzes the existing digital image watermarking algorithm based on Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT); hybrid transform 2-D transform (DCT-DWT), with definitions, properties and algorithm is developed. Finally, the watermarking algorithm based on (DCT-DWT) is advanced. Simulation illustrates the application.
