Detailed Documentation
This project implements the Least Significant Bit (LSB) watermarking algorithm, a widely-used technique for digital image watermarking. The compression package includes original test images that can be directly loaded into MATLAB for execution and analysis. The implementation modifies the least significant bits of image pixels to embed watermark data while maintaining visual quality. Key functions include image preprocessing, bit-plane manipulation for watermark insertion, and extraction algorithms for recovering hidden data. This method effectively balances image preservation with robust digital watermark embedding and extraction capabilities, demonstrating practical applications in copyright protection and data security.
