说明：  一个简单的画图程序，提供基本图元点、线、面，图元填充、裁剪的操作(Simple Draw)

矫正桶形畸变，只是用了坐标变化，目前在研究张正友的算法，日后会上传的(correct the distortion of picture)

说明：  按照最邻近原则把待分类样本点分到各个簇。然后按平均法重新计算各个簇的质心，从而确定新的簇心。一直迭代，直到簇心的移动距离小于某个给定的值。(According to the nearest neighbor principle, the sample points to be classified are divided into clusters. Then the centroid of each cluster is recalculated according to the average method to determine the new cluster center. Iterate until the moving distance of the cluster center is less than a given value)

Lee的经典的多分辨率B样条拟合方法（multi-level B-spline fitting）的VC源代码。广泛应用于图形图像处理，CAD等领域。(Lee s classic multi-resolution B-spline fitting method (multi-level B-spline fitting) of the VC source code. Widely used in graphic image processing, CAD and other fields.)

对于传统去噪模型的大幅改进，之前的模型都会出现阶梯效应的现象，采取了新的模型对图像进行建模，有效改善了图像去噪图像修复等过程中引入的阶梯效应，而且一定程度上对于图像纹理的修复也有很大的作用(For significantly improve the traditional de-noising model, the model will appear before the phenomenon of the staircase effect, to take a new model for image modeling, effectively improved the staircase effect denoising image restoration process introduced, and to a certain extent for texture of repair also has a significant role)

利用霍夫变换进行椭圆检测，无需模板，不同的图片只需要更改个别参数(Ellipse detection using Hough transform, without templates, a different picture only need to change individual parameters)

用于Landsat5 TM数据的辐射定标(Calibration for Landsat TM data using IDL)

平时工作中常会遇到需要处理图片的工作，这个是判断并修改图片分辨率的python方法。(Usually work the Central Standing Committee met to deal with the work of the picture, this is a python method to determine and modify the image resolution.)

2012实习，新鲜的matlab实现水印的嵌入和提取，包括盲水印提取代码(watermark embedding and extraction, including the blind watermark extraction code)

泊松图像融合算法的实现，这是我自己写的，很多地方可以改进，希望对学习这方面的有帮助(poisson image editing)
