光流法，经典的LKPR-marzat算法，适合研究光流法的学者使用，可执行，无错误 (Optical flow method, the classic LKPR-marzat algorithm, for research scholars to use optical flow method, executable, error-free)

这是一份关于数字图像处理半色调打印技术的MATLab源程序。(This is a paper about Halftoning.)

对形图像的经过边缘提取后得到的二值图像边缘进行细化，提取单像素的边缘，使得边缘是成为清楚的单像素的边缘。(After images of the shape after the edge extraction of the binary image to refine the edge, the edge extraction of a single pixel, making the edge is to be clear of the edge of a single pixel.)

Itti模型的显著图提取，使用matlab编写，很好的代码，可供参考学习(Itti model saliency map extraction, the use of matlab prepared very well the code)

双线性插值算法是一种空间域的错误掩盖算法，本程序实现了用双线性插值算法恢复受损图像的matlab程序(Bilinear interpolation algorithm is a spatial domain error concealment algorithm to achieve this program using bilinear interpolation algorithm to restore damaged image matlab program)

总变分正则化超分辨率重建 包括两种范数形式的正则化(Total Variation Regularized super-resolution reconstruction, including two-norm in the form of regularization)

混合高斯分布EM算法，可以算混合高斯分布的三个参数。混合高斯分布更接近系数分布。(mixed Gaussian distribution EM algorithm can calculate mixed Gaussian distribution of the three parameters. Mixed closer to the Gaussian distribution coefficient.)

本方法的种子点选取采用Harris角点法，阈值则通过云模型获得，对lena图像进行了较好的分割(The method selected seed points using Harris corner point method, the threshold is obtained through the cloud model, for better lena image segmentation)

对圆形物体图像进行图像边缘检测，图像分割，检测及圆拟合(Images of circular objects in image edge detection, image segmentation, detection and circle fitting)

说明：  读取nc文件，可画出温度，盐度，水深和流场图(it can read NC files, and then draw the map of ocean water depth, temperature, salinity and flow quiver field)
