By using the human psychology and vision model , we embed visible and invisible watermarking into an image , which can provide dual protection for digital image copyright 利用人类心理学、视觉模型，在一幅图像中嵌入可见和不可见两种水印，结合这两种水印的优点，给数字图像版权提供双重保护。
We adjust the strength of embedded watermark in according to the visual model in the ridgelet domain . experimental results show that our algorithm is very effective . performance improvement is obtained 论文根据小脊变换域中的视觉模型，按照小脊变换域中计算出水印嵌入强度的权重，用扩频的方法来嵌入水印信息。

Ridgelet transform decompose the spatial frequency domain into some subbands with different directions and frequencies . this hierarchy matchs the multi - channel model of hvs ( human visual system ) better than wavelet transform 由于小脊变换的特点，使得在小脊变换域中建立视觉模型比在dct 、 dwt域中建模更自然，更有优势。
Afterwards we discuss the human vision model ( hvs ) in space domain and dct domain respectively ; we provide some algorithms to embed the information using the hvs models , analyzing the algorithm flow and correctness of the extracted data 我们还根据这两个模型得出的数据提出了一些利用人眼视觉模型的隐藏算法，分析了算法流程以及数据的提取正确性。
Then we make a deep research on human visual system and wavelet transformation , and a new wavelet watermarking method based on hvs is proposed to solve the conflict between robustness and imperceptibility 在此基础上，论文又将人眼视觉系统和小波变换结合在一起，提出了一种基于hvs的小波水印算法，人眼视觉模型的应用缓解了算法鲁棒性和不可见性间的矛盾。
The analysis for the visual features of color image and the transformation between the color visual model and the industry color model , the system design for color image segmentation based on the human vision are presented in the fifth chapter 第五章探讨了彩色图像的视觉特性,彩色视觉模型与工业彩色模型之间的转换,提出了基于视觉特征的彩色图像分割系统设计。
Jpeg2000 is based on wavelet transform which provides multi - resolution analyses similar to the multi - channel decomposition of human vision . in this paper , we firstly summarize the basic principles and some popular methods of digital image compression 由于jpeg2000是基于小波变换的编码，提供了类似人类视觉系统的多通道空频分解，为视觉模型应用提供了一个良好的平台。
Due to the future of wavelet transform is accordant with the human visual model ( hvs ) , a watermark can be embedded into an image by using wavelet transform , and its covered effect is apparently superior to the one inset by using other way 这样就克服了小波时间分辨率高时，频率分辨率低的缺陷。由于小波变换与人类视觉模型的特点相符合，故用小波变换在图象中嵌入水印，其隐蔽性较其他方法具有明显优越性
