Calculate color difference in CIELAB color space dE 94 and dEab 94

说明：  MATLAB 工具包 很不错的东西 (MATLAB tool kit is a good thing)

matlab 灰色预测模型 适用于预测模型(matlab gray prediction model is applicable to prediction model)

2D-Gabor变换的Matlab实现代码(Codes of Matlab for 2D-Gabor transform)

主要是基于mtlab的程序，基于多相结构的信道化接收机，分数阶傅里叶变换计算方面。( Mainly based on the mtlab procedures, Channelized receiver based on multi-phase structure, Fractional Fourier transform computing.)

This code is a complete fingerprint core point detection. It uses orientation field for singular point detection and Zhang-suen algo. for thinning in preprocessing part

document example example

matlab实现相关器，用相关原理检测噪声中的微弱信号(matlab implementation correlator with the relevant principles of weak signal detection in noise)

实现ID3算法，在结果中以树表示出来。决策树是对数据进行分类，以此达到预测的目的。该决策树方法先根据训练集数据形成决策树，如果该树不能对所有对象给出正确的分类，那么选择一些例外加入到训练集数据中，重复该过程一直到形成正确的决策集。(ID3 algorithm to achieve, in the results that come out to the tree. Decision tree is to classify the data, thus achieving the purpose of prediction. The decision tree training set of data according to the formation of the first decision tree, if the tree can not give the correct classification of all objects, then select a number of exceptions to the training set data, repeat the process until the correct decision set.)

说明：  NCUT图像分割matlab代码，实现图像分割的较好的方法(NCUT image segmentation matlab code to achieve a better method of image segmentation)
