Resource Overview
MATLAB implementation of Cox method frequency-domain watermarking technique for embedding information in bitmap images
Detailed Documentation
This implementation provides MATLAB source code for the Cox method spread spectrum watermarking technique, designed to hide information within bitmap images. The algorithm operates in the frequency domain by modifying selected DCT (Discrete Cosine Transform) coefficients to embed watermark data. Key implementation features include DCT transformation of image blocks, coefficient selection based on perceptual significance, and watermark embedding through additive spread spectrum techniques. The method enhances privacy protection and image security through robust watermark embedding that maintains visual quality while resisting common image processing operations. The code includes functions for both watermark embedding and extraction processes, making it suitable for various applications including digital rights management and authentication systems.
