摘要 一种基于图像分块和视觉特性的数字水印嵌入技术将水印信息嵌入到静止图像中,该方法应用双重DCT方法实现了较大的嵌入量和良好的隐蔽性.实验表明,这种方法能够抵御噪声干扰、线性滤波和JPEG压缩编码,具有良好的应用价值. A digital image watermarking technique is introduced. Image blocks are first classified into four categories according to human visual system and image block characteristics. Data are then embedded using a dual DCT scheme. Experimental results show that the proposed technique can resist noise interference, linear filtering, and JPEG compression.
