研究了一种图像水印技术, 该算法利用人类视觉系统( HVS)的特性, 根据JPEG量化表自适
应地调整, 采用随机置乱变换的方法进行空域关系调整, 将水印嵌入到图像的DCT 低频分量中-A kind of image watermarking techniques, the algorithm uses the human visual system (HVS) characteristics, according to adaptively adjust the JPEG quantization table, the random method of scrambling transformation of spatial relationship adjustment, the watermark is embedded into the image of the low frequency DCT in
