skin detector can detect skin color

基于matlab 设计的滤波器程序，很实用。内容包括 FIR数字滤波器的设计、IIR数字滤波器的设计、FFT频谱分析及应用等。(wave filter of matlab )

说明：  利用matlab的gui设计的带有输入和输出功能的界面图形，可视性很强，自己独立编写，学习非常值得(Uses the Matlab GUI design to have the input and output function the interface graph, the visibility is very strong, writes independently, the study is very worthwhile.)

描述变论域模糊控制的重要论文，相信对研究变论域的朋友有帮助(Describe the variable universe fuzzy control of key papers, I believe that the study of variable universe of friends to help)

说明：  bp神经网络预测模型，可以很好的进行训练集和测试集建模，实用方便(BP neural network prediction model can model training set and test set very well, which is practical and convenien)

A {@code CharacterCodingException} is thrown when an encoding or decoding error occurs.

stochastic subspace identification code

本附件包含在matlab环境下双谱分析源码的m文件，除了高阶谱，是用的比较广泛的一种。主要用于TDOA及弱信号检测等。可以动手下载后在matlab下运行之。和我前次发的高阶谱分析帖子一样，是要手动加入matlab高阶谱工具箱！ (This annex is included in the matlab environment bispectral analysis of source code of m documents, in addition to high-end spectrum, is widely used as a comparison. Mainly for TDOA and weak signal detection. Can begin download matlab running it. And my previous post issued order spectral analysis, is to manually add order spectrum matlab toolbox!)

An example case is considered to price an option at a maturity of T years - prices are simulated for Geometric brownian motion process at 2*T maturity, and Brownian Bridge is used to obtain prices at T maturity. Finally option prices are compared to Black Scholes values to verify results(An example case is considered to price an option at a maturity of T years- prices are simulated for Geometric brownian motion process at 2*T maturity, and Brownian Bridge is used to obtain prices at T maturity. Finally option prices are compared to Black Scholes values to verify results)

文中的方法是把图像分块，小波分解得到低频分量、高频分量，然后计算每一块的对比度，把图像块划分为清晰块、模糊块，把清晰块和模糊块相邻的区域定义为边界区域，融合时，直接选取清晰块作为融合后的相应块，对于边界区域，在小波分解的基础上采用基于对比度的像素选取的方法进行处理。(Paper, the method is to image segmentation, wavelet decomposition are low frequency, high frequency components, then calculate the contrast of each piece, the image block is divided into clear blocks, fuzzy block, to clear blocks and fuzzy block is defined as the border region adjacent to area, integration time, a clear block directly select the corresponding block as a fusion, for the border region, the wavelet decomposition on the basis of the pixel-based contrast method selected for processing.)
