The Second-Generation Bandelet KICA-Based Digital Watermarking Algorithm

In order to improve the effect of the embedding of watermark, this paper the second generation Bandelet to transform the watermark. The Kernel Independent Component Analyzes (KICA) have good robustness in the watermark extraction aspect, so in this article the Kernel Independent Component Analysis (KICA) theory was introduced to the digital watermark extraction. By using different attacking on the watermark embedding image, the experimental results show that the proposed second-generation Bandelet KICA-based watermarking algorithm has better robustness.
