The Detection for Image Spread Spectrum Watermarking Based on Self-Adaptive Wavelet Transform by DSP
Lian Jun Zhang · Advanced materials research · 2012
The relation between the digital watermarking and spread-spectrum is analyzed in this paper at the beginning. Then, a spread-spectrum adaptive digital watermarking scheme based on the wavelet transform is proposed and the system for this digital watermarking algorithm based on DSP is realized. Finally, a testing on the image digital watermarking processing system by DSP is conducted. The result from the testing approves that the system is flexible and can accomplish watermark embedding and detecting.
