用于无参考帧图像质量评价的MATLAB程序，运行程序为example，输出图像的客观分值。(This is the matlab code of no-reference image qualituy assessment in space domain, th result ofthe program is the object acore of the image.)

基于SVD的DCT域和DWT域的经典水印算法，该算法通过提取水印水印的主成分并把该主成分嵌入到奇异值矩阵，鲁邦性非常高。(the principal components of the watermark are embedded into the host image in discrete cosine transform (DCT) and for the second method, those are embedded into the host image in discrete wavelets transform (DWT). To improve the robustness, the particle swarm optimization (PSO) is used for finding the suitable scaling factors. )
