图像特征识别通过神经网络训练方法实现，是学习参考的好资料-you will need first to run the file that name "charGUI4.fig" and on the right side there is a load training set where you have to train the system first, run any data that is should be from 1 to 9 and 0 like ( 1 2 3 4 5 5

国外编写的双树复小波的一个开发包，包括1维和2维的情况，文件中有说明。-The Dual-Tree Complex Wavelet prepared outside of a development package, including the one-dimensional and two-dimensional case, the document has made it clear.

Hidden-Unit Conditional Random Fields 工具箱，可以用于训练linearCRF和和L.J.P. van der Maaten, M. Welling 提出的huCRF-We provide Matlab code that implements the training and evaluation of hidden-unit CRFs, as well as code to reproduce the results of our experim

2.编写两类正态分布模式的贝叶斯分类程序。 设以下模式类别具有正态概率密度函数： ω1：{(0 0)T, (2 0)T, (2 2)T, (0 2)T} ω2：{(4 4)T, (6 4)T, (6 6)T, (4 6)T} （1）设P(ω1)= P(ω2)=1/2，求这两类模式之间的贝叶斯判别界面的方程式。 （2）绘出判别界面。 3.已知服从正态分布的两类训练样本集分别为 ：，，，， ：，，， ，试问属于哪一类？
