摘　　要：数字水印是一项热点技术,主要应用于版权保护和信息安全方面,有诸多特点。数字水印技术具体来说就是将一些有特点的信息直接放入图片或者视频里,不会影响原图片或者视频的观感和使用价值。文章研究了基于独立分量分析方法的空域水印模型,并分别进行独立分量分析实现对水印的提取和嵌入,得出了对比后的结果。实验表明,对独立分量分析的空域水印进行提取效果一般,不过在嵌入的时候效果很好。Digital watermarking is a hot technology mainly applied in copyright protection and information security,with many characteristics.Digital watermarking technology specifically refers to the direct insertion of characteristic information into an image or video,without affecting the appearance and usefulness of the original image or video.The article studies a spatial watermarking model based on independent component analysis method,and performs independent component analysis to extract and embed watermarks,obtaining the results after comparison.Experiments have shown that the extraction effect of spatial watermarks using independent component analysis is average,but the embedding effect is very good.
