BM3D
- The Block-Matching and 3D Filtering (BM3D) algorithm is a computationally scalable algorithm based on this novel denoising strategy. It achieves state-of-the-art denoising performance in terms of both peak signal-to-noise ratio and subjective visual
Method-of-Converting-Speech-Codec-Formats-between-
- Abstract - In this paper, proposed an efficient method of converting speech codec formats between G.723.1 and G.729А. The proposed method is composed of four steps: LSP conversion, pitch conversion, adaptive codebook search and fixed cod

- 在现代化的评价模型中，我们可以用层次分析法建立模型，但是其主观性强，判断矩阵的确定比较困难-In the modern evaluation model, we can use AHP model, but its subjective nature, is difficult to determine the matrix to determine the
Nouveau-dossier-(2)
- brightness : Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light.[1] In other words, brightness is the perception elicited by the luminance of a visual target. This is a subjective attribute/p
SingularityIndex
- 基于自然场景统计的无参考图像质量评价，此方法可以很好的评价图像质量，与主观评价匹配性很好-No statistics are based on natural scene reference image quality assessment, the evaluation of this method can be very good image quality, very good match with the subjective evaluation
层次分析法
- 对不同的因素进行层次分析决断，更好的通过主观判断得出希望的结果(Make analytic decision on different factors, and get better result through subjective judgmen)
ccfci
- 在大量的评价体系中，都用到了层次分析这一方法来确定权重，虽然它主观性很强，但简单易懂，在国内广泛应用。本程序是调试好的层次分析程序，可以直接使用。(In a large number of evaluation system, have used the method of level analysis to determine the weight, although it is subjective, but easy to understand, widely used in the co
