基于Arnold变换和采样理论的置乱技术-Based on Arnold transform and sampling theory Scrambling Technology

Compressive sampling is an emerging technique that promises to effectively recover a sparse signal from far fewer measurements than its dimension. The compressive sampling theory assures almost an exact recovery of a sparse signal if the signal is se

基于直方图的水印嵌入和提取实现，各种水印攻击，如重抽样，加噪，滤波，尺度变换，局部裁剪-Based on the histogram of the watermark embedding and extraction to achieve a variety of watermark attacks, such as re sampling, noise, filtering, scale transform, local cropping
