variance

图形图像处理中的平滑处理，可以实现部分的功能，但是还可以继续完善(Graphic image processing smoothing, can achieve some of the functions, but can also continue to improve)

chan和vese的多水平集算法，可以用2条初始水平集来演化，从而达到检测多目标的目的。(chan and the multi-level set algorithm, you can use two sets to the initial level of evolution, so as to achieve the goal of multi-purpose.)

Ncut的文献及matlab源代码。基于图的分割非常好的一个算法(Ncut literature and matlab source code. Graph-Based Segmentation Algorithm for a very good)

图像分割程序，采用水平集演化的思想，实现偏微分方程中的GAC模型。Image segment source code(GAC model),which adopt the idea of level set evolving.(Image segmentation procedures, the use of level set evolution of thought, the realization of partial differential equations of the GAC model. Image segment source code (GAC model), which adopt the idea of level set evolving.)

说明：  转载的，通过眨眼前后灰度图对比是别人眼，一个学习opencv工具的好例程。(Reproduced by blinking eyes of others around the grayscale contrast, a learning tool opencv good routine.)

主动轮廓模型也就是snake模型进行图像分割，一种由图像高层信息的图像分割算法。(snake model，active contour model，image segmentation)

毕业设计的程序 用VC++6.0做的 主要是测试几个边缘检测算子的效果(Graduate programs designed to use VC++ 6.0 to do is to test several of the main edge detection operator effect)

说明：  水表图像识别 图像预处理 哈哈就不懂四周(Water Meter Image Recognition)

维纳滤波和均值滤波，及利用自适应维纳滤波的图像去噪MATLAB代码，效果优于维纳滤波(Using adaptive Wiener filtering for image denoising MATLAB code, the effect is better than Wiener filtering)

图像处理中，相机坐标系和世界坐标系的转换(transfer from camera coordinate to world coordinate)
