【2D Graphic】 COLORPSNR DL : 0: 此程序用C语言求取彩色图像的PSNR。psnr是一种评价图像的客观标准。它具有局限性，PSNR是“PeakSignaltoNoiseRatio”的缩写。peak的中文意思是顶点。而ratio的意思是比率或比列的。整个意思就是到达噪音比率的顶点信号，psnr是一般是用于最大值信号和背景噪音之间的一个工程项目。-This program uses the C language to strike a color image PSNR. psnr is an objective criteria to evaluate image. It has limitations, PSNR is "PeakSignaltoNoiseRatio," the abbreviation. the peak of the Chinese meaning is the vertex. The ratio of the mean ratio than the column. The means to reach the vertex of the noise ratio signal, and psnr is generally used for a project between the maximum signal and background noise。

【Other】 A1L-A02 DL : 0: Based on the idea to exploit the statistical dependencies from both temporal and inter-view reference pictures for motion compensated prediction, this paper presents a sys- tematic evaluation of multi-view video coding with opti- mized prediction structures. The compression method is based on the multiple reference picture technique in the H.264/AVC video coding standard. The advantages of hier- archical B pictures for temporal prediction are combined with inter-view prediction for different temporal hierarchy levels, starting from simulcast coding with no inter-view prediction up to full level inter-view prediction. When using inter-view prediction at key picture temporal level average gains of 1.4 dB PSNR are reported, while additionally using inter-view prediction at non-key picture temporal levels av- erage gains of 1.6 dB PSNR are reported. For some cases gains of more than 3 dB, corresponding to bit rate savings of up to 50 , are obtained.-Based on the idea to exploit the statistical dependencies from both temporal and inter-view reference pictures for motion compensated prediction, this paper presents a sys- tematic evaluation of multi-view video coding with opti- mized prediction structures.

It is a difficult problem to simultaneously fill-in the texture and structure in regions of missing image information. In order to inpaint the damaged image with both missing the structure and texture information, an image inpainting algorithm based on wavelet decomposition is presented. First the damaged image is decomposed into structure sub-image and texture sub-image using the wavelet transformation. Then, the sub-image with the region of missing information in the structure is reconstructed by Curvature-Driven Diffusions (CDD) algorithm, while the same region in the texture sub-image is filled-in with the improved texture synthesis based on exemplar Finally, the restored image is given by recombining the structure and texture restored results. A large number of experiments show that the proposed algorithm can quickly and efficiently restore the structure and texture information at the same time, and the visual eff
