人眼视觉模型 meaning in Chinese
hvs
Examples
- Digital watermarks based on the human visual system
基于人眼视觉模型的图像水印技术 - By utilizing the just noticeable distortion ( jnd ) values , the transparency of the hidden watermark can be guaranteed
算法中引入了人眼视觉模型，使得算法有好的视觉隐蔽性。 - 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。 - 3 . utilizing the hvs and the characteristic which integer wavelet analyzes the high - frequency coefficient to express the image detail , proposed the definition of energy coefficient . according to the sub - blocks from different groups , the computed energy coefficients were different
3 .利用人眼视觉模型和整数小波分解后高频系数表示图像细节的特性,提出了能量系数的定义,根据不同组的子块,计算出的能量系数是不相同的。
