中文摘要：
容量是隐形图像水印最基本的要求之一，为了提高水印的嵌入容量，提出了一种新的基于编码的预处理方法．首先对待嵌入的水印信息进行压缩编码和差错控制编码，然后将编码后的水印序列嵌入到载体图像的DCT系数中．理论分析和仿真结果表明，采用编码的预处理方法，有效地提高了水印系统的容量，且具有较好的不可见性，对一些常见的攻击（如高斯噪声、低通滤波、JPEG压缩）有很好的鲁棒性．
英文摘要：
Capacity is one of the most basic requirements for invisible image watermarks. To improve the capacity of watermarks, a new watermarking pre-processing method based on coding is proposed. Firstly, the water mark information is pre-processed by compression coding and error control coding （ECC）. And then, the coded watermark sequence is embedded in the discrete cosine transform （DCT） coefficients of carrier image. Theoretical analysis and simulation results show that the watermarks generated with the proposed method are invisible and robust against noise and commonly used image processing techniques, and have higher capacity.
