图像保真度 meaning in Chinese

eyefidelity

Experiments show that choosing frequency domain to embed watermarking can gain image fidelity better and have more robustness than watermarking embedded algorithm in space domain
实验证明选择频域嵌入水印可以获得更好的图像保真度并且比在空域中的水印嵌入算法更稳健。
The popular fidelity measurement method based on root mean squared error ( rmse ) is unable to completely reflect the details of the sensitive information of compressed grayscale images
摘要常用的基于均方根误差( rmse )图像保真度准则不能准确地放映一些灰度图像主要敏感细节。
With the multi - resolution analysis of wavelet and the vision character of the human eyes we decompose the image in wavelet domain , which can get better image and is more robust than the arithmetic embedded with hid information in airspace
利用小波变换的多分辨率特性并结合人眼的视觉特性来进行图像的小波域分解，这样可以获得更好的图像保真度并且比在空域中的隐藏信息嵌入算法更稳健。
