visual masking

基本解释

A digital watermarking method utilizing human visual masking was proposed in this paper.
本文提出了一种利用人类视觉掩盖效应的数字水印技术。
Aiming at different quality effects on different image region and distortion type, we take full advantage of the visual masking effect and proposed a new weighted idea.
充分利用人眼视觉掩盖效应，针对不同的失真类型对于图像不同的内容具有不同的质量影响，提出了一种新的加权策略。
A visual masking model is presented by analyzing the human visual characteristics, then embeds watermark in the typical image of "Lena" by low frequency coefficient of DCT.
通过分析人的视觉特性提出一种视觉掩盖模型，得到该模型水印嵌入算法和水印检测算法。

视觉掩蔽
A visual masking function is used to modify the digital signature to assure the perceptual quality of the watermarked image.
用一个视觉掩蔽函数来修改水印图像,保证了嵌入水印后的宿主图像的视觉质量。
视觉掩盖
In the proposed method,the SSIM values are calculated with the different weighted values fused visual characteristics including contrast sensitivity,multi-channel structure,visual masking and so on.
该方法是在结构相似(SSIM)方法基础之上,融合了人眼几个主要视觉特性,如对比敏感度、多通道、视觉掩盖、视觉非线性等。
