关于数字图像处理的PPT，里面包含一些C++，MATLAB实现等等，对于学习数字图像处理非常有帮助(On the digital image processing PPT, contains some c++. MATLAB, and so on, to learn the digital image processing is very helpful )

训练错误率和交叉验证错误率相等，在样本比较大时，这个结果是可以预期的；训练错误率一般低于测试错误率，但是当样本数据比较少时，实验也出现了意外，样本多的那组测试错误率比样本少的训练错误率还要小；在本实验中，同组数据的交叉验证错误率比独立测试错误率高，这个反常现象是因为样本的原因所致，交叉验证的样本小，而独立测试时所用训练样本数目大，因而出现这种情况。分类线上，fisher准则是一条直线，而贝叶斯分类器实际上是一个类似椭圆的封闭曲线；很明显，贝叶斯分类器比fisher分类器要好。(Training error rate and cross- validation error rates are equal, the larger the sample , this result is to be expected training error rate is generally lower than the test error rate , but when comparing the sample data came from the experiment there was an accident, that more samples group test error rate less than the training sample error rate is smaller In this experiment, the same set of data cross-validation error rate than independent test error rate, this anomaly is because the sample of reasons , cross-validation sample is small,And independent testing large number of training samples used , resulting in this situation.Classification online , fisher criterion is a straight line , while the Bayesian classifier is actually a closed curve similar to elliptical It is clear that the Bayesian classifier is better than the fisher classifier .)

利用类处理异常，实现根据异常处理规则，进行异常捕获(The use of unusual types of processing to achieve exception handling in accordance with rules capture abnormal)

比较生存曲线可以用统计假设测试日志秩检验。它是用来测试的零假设，没有任何区别的人口的生存曲线（即概率事件发生在任何时间点是相同的每个人口）.这个函数使用卡普兰曲线的程序来估计生存函数.(Comparison of two survival curves can be done using a statistical hypothesis test called the log rank test. It is used to test the null hypothesis that there is no difference between the population survival curves (i.e. the probability of an event occurring at any time point is the same for each population). This function use the Kaplan-Meier procedure to estimate the survival function, so it is mandatory to download )

说明：  图像抽取及误差控制，像素点最大误差能控制到2(Image extraction and error control, the maximum pixel error can be controlled to 2)

说明：  一个老外写的关于图像融合的MATLAB代码，实现将一只人眼融合到手掌心(multiband_blending_matlab_code)

说明：  一种基于matlab编写的免疫遗传算法程序，比较好，不过我看不懂，请高手指点。谢谢！(prepared by the immune genetic algorithm procedures, better, but I do not understand, please master guiding. Thank you!)

该程序可以用作计算谐振器的传输特性，包括透过率、相移、色散、延迟等。(describe resonator)
