[Special Effects] PSF DL : 0: 本文针对灰度图像的盲复原问题进行了一些研究，介绍了两种不同的图像盲复原处理的方法。一种是误差一参数分析法，该方法适合于辨识可以用参数来表征的点扩散函数，如线性移动模型和Gauss模型等，然后根据估计的参数确定退化图像的点扩’散函数，再利用常规的复原算法(如维纳滤波法)对退化图像进行复原处理另一种是非负支撑域约束递归逆滤波(NAS-R工F)算法，文中介绍了NAS-R工F算法的基本思想，并结合正则化的思想，提出了NAS-RIF的改进算法，相应对该算法的性能效果进行了仿真分析。 1.图像去噪MATLAB仿真程序.m 2.图像点扩展函数获取MATLAB仿真程序.m 3.约束最小二乘法图像复原MATLAB仿真程序.m

[Special Effects] Programs DL : 2: 2、图像增强：图像增强也称为图像锐化，其目的是为了加强图像中的轮廓边缘等细节信息。与图像平滑一样，也可分别在空域和频域进行图像增强。在空域中进行图像锐化：将原图像与相减可以得到经过锐化处理的图像g(i,j)，即： g(i,j)= f(i,j)- = f(i,j)-α[f(i+1,j)+ f(i-1,j)+ f(i,j+1)+ f(i,j-1)-4 f(i,j)] = f(i,j)+4α[f(i,j)- ] 这里，α为可选择的用于控制锐化程度的因子，其中,1/4 是被锐化处理点的周围4邻点之灰度的平均值。原图像经过锐化处理后，灰度变化较平坦的区域，变化不大，而包括轮廓点在内的灰度变化较剧烈的区域，灰度差别加大，即图像细节得到增强。也可以在频域进行图像的锐化处理。-err

[Special Effects] Extending_Anisotropic_Operators_to_Recover_Smooth_ DL : 0: 采用各向异性方法填补一个缺损的轮廓，从而可以得到一个光滑完整的轮廓。- Completed contours correspond to ridges of an extension (ext) of the characteristic function of the uncompleted curve. Anisotropic extension is performed on the characteristic function fbound of an image set given by the binary map boundary to the whole image domain. Extension is initially driven by \xi=(EigVect{1}, EigVect{2}) (which should match with the contour tangent direction) computed as the direction of maximum coherence of the distance map to the contour to close. It is updated every N iterations with DCV over the distance map to the ridges/thinning of the evolved image. Two different stop criteria are supported: Number of Connected Components ( numcomp ). Contour Completion. Stop when the extended contour (curve of level 1) has exactly Ncomp connected components. Difference between two consecutive iterations ( tol ) Speed Stabilizes ( speed_stab ).

[Special Effects] BasedonprincipalcomponentanalysisoftheFaceRecognit DL : 0: 在特征提取阶段，研究了PCA, 2DPCA, (2D) 2PCA, DiagPCA, DiagPCA-F-2DPCA等多种方法。不同于基于图象向量的PCA特征提取，由于2DPCA, (2D) ZPCA, DiagPCA和 DiagPCA-I-2DPCA的特征提取都直接基于图象矩阵，计算量小，所以特征的提取速度明显高于PCA方法。-In the feature extraction stage, the study of the PCA, 2DPCA, (2D) 2PCA, DiagPCA, DiagPCA-F-2DPCA and other methods. Vector is different from the PCA-based image feature extraction, as 2DPCA, (2D) ZPCA, DiagPCA and DiagPCA-I-2DPCA the feature extraction are directly based on image matrix, a small amount of calculation, so the speed of feature extraction method was significantly higher than PCA .
