基于活动轮廓模型的图像分割算法研究，是其中一些子程序，适合初学者研究(Active contour model based image segmentation algorithm, are some of the subroutine, suitable for beginners of)

使用matlab语言编写的，用于直方图法的分析，也可以称作众数法(Using matlab language, for histogram analysis method can also be called a modal method)

the code file that is uploded is myvad file

该代码对给出的一副图像进行了图像的重构，优化了图像的画质。(The code given an image reconstruction of the image to optimize the quality of images.)

这里介绍了VC与matlab的简单联合运用，初步学会结合(Here are the simple joint use of the VC and Matlab, initially learned to combine)

基于MATLAB的电力系统短路计算仿真,希望对大家有用。(Based on the MATLAB power system short circuit calculation simulation, I hope it useful for you。)

为了对数据进行准确的预测，建立了双隐层BP神经网络，并提供了源数据，实现了准确的数据预测。程序能够执行，误差较小，输出接近真实值。(To accurately forecast the data, we build the two-hidden layer BP neural network and provide the original data, which will forecast the data. The program can be executed with small error which will be close to the real data.)

template matching using corr2 function in matlab working very well
