说明：  光子晶体带隙计算的例子，以前在3.5版本模型库里面有，但是4.2里面么了，希望对大家有所帮助。(Photonic band gap calculation example, the previous 3.5 version of the model library in there, but what a 4.2 inside, we want to help.)

彩色数字水印的程序，实现在彩色图像中通过DCT变换来嵌入水印信息(Color digital watermarking process to achieve the color image by DCT transform to embed watermarks)

Performs huffmann coding

说明：  image processing and noise models

实现图像的显著性，真正的原始代码，非修改，来自于外国著名实验室。(saliency map)

通过给定天线阵列的参数，计算出切比雪夫馈电电流分布，并计算出方向图(By giving the parameters of the antenna array, the current distribution of the Chebyshev feed current is calculated and the direction map is calculated.)

matlab程序30个基础小例子，非常适合初学者学习和了解。(matlab program 30 based small example, very suitable for beginners to learn and understand.)

基于阈值分割心音信号，阈值可根据信号调整，程序给出心音分割的起止位置。(Threshold-based segmentation of heart sound signals, the threshold can be adjusted according to the signal, the program gives the starting and ending positions of heart sounds segmentation.)

对图像加模糊，并用倒谱法实现对所得模糊图像的模糊参数估计(Additive fuzzy image, and cepstral method from fuzzy images of the fuzzy parameter estimation)

A image with bad contrast is hard to be segmented. So this function analysis the RGB chennel, find the worse distributed chennel and fix it , then the result is a normal contrast image
