svt is algorithm that calculate a matirx from the part of it s elemets . it is can be applied to image processing when part image was lost.是一个算法，知道部分矩阵元素，计算整个矩阵的方法。该方法主用是借助奇异值分解和Bregman算法，可很快完成计算。可以用于图像数据缺损的情况。

Newton- Rapson method for optimization

梯度下降法的matlab版本实例,带收敛轨迹图。(the steepest descent algorithm with matlab )

用Hausdorff距离对两角点集进行配准，得到点集间的仿射变换，从而实现图像的自动配准。此算法以角点作为Hausdorff距离的配准特征，与直接选用边缘来配准的方法相比较，大大减小计算量。(Hausdorff distance on the corners with a point set registration, be affine transformation between sets in order to achieve automatic image registration. This algorithm is based corner as the Hausdorff distance matching characteristics, and use Edge to direct registration method of comparison, greatly reduced computation.)
