这是我们参加2011年全国大学生数学建模大赛，做A题的论文和matlab程序，当年获得国奖。 利用此程序可以进行污染源位置反演计算，以及其他类似服从高斯扩散模型的源项反演。 计算量小，简单易懂。(Detect of Pollution source in city.2011 China Undergraduate Mathematical Contest in modeling Q_A.)

In this project, Brain tumor in MRI is detected using image segmentation techniques. There are number of image segmentation techniques available but watershed segmentation is considered to be best among all. First of all prep-processing is to be done on MRI image followed by Segmentation. During pre-processing, MRI is first converted into gray scale image then salt and pepper noise is removed using median filter. Image is then enhanced using Histogram Equalization then Image segmentation is performed on image. In image segmentation, image is segmented into its constituent parts. In this way, brain tumor is detected.

B样条曲线生成程序,HHT插件等。rilling版本，供大家参考学习。 (B-spline curve generation procedures, HHT, such as plug-ins. rilling version for your learning.)

用于添加噪声，达到去噪的目的.原始数据如果不太理想，去噪是常用的处理方法(Used to add noise to achieve the purpose of de-noising. If the original data is not ideal, de-noising is a common treatment method)

机加工自由曲面，由matlab生成设计曲面和设计刀具轨迹（此例为加工椭球面）(Freeform surface machining, surface generated by the matlab design and design tool path (in this case for the processing of the ellipsoid))

电磁暂态计算用EMTP的rule手册，英文版本，中文版翻译不是很好，还是得看英文版(atp emtp rule book ,english version)

用matlab写的图像预测编码，compress.m是压缩，descompress.m是解压缩。(Using matlab to write the image predictive coding, compress.m is compressed, descompress.m is extracted.)
