说明：  基于matlab的语音信号处理快速傅里叶变换程序(Fast Fourier Transform Program for Speech Signal Processing Based on MATLAB)

包含了主要的图像质量评价的matlab源程序。图像熵，图像的方差和，以及基于边缘检测算子的质量评价函数。(Contains the main image quality evaluation of the matlab source code. Image entropy, variance and images, as well as edge detection operator based on the quality of the evaluation function.)

说明：  my_noise文件是已知信号方差，加入信号噪声，可以加入高斯噪声，淑盐噪声,等其他噪声十分有用 其他两个函数时加入噪声信噪比SNR,但是有一点,这种方法并不准确,不能保证加入噪声信噪比为SNR,实际测试中可以看出,但是可以加入相同的信噪比的噪声(my_noise document is known to signal variance, by adding signal noise, Gaussian noise can be added, suk salt noise, noise, and other very useful function when the other two noise signal to noise ratio SNR, but there is one point, this method is not accurate , can not be guaranteed by adding the noise signal to noise ratio for the SNR, the actual test can be seen, but can join the same noise signal to noise ratio)

一种基于Arnold变换的图像加密技术，并且用Matlab的GUI界面设计一个用Arnold算法进行图像加密的程序。该程序实现了Arnold图像加密算法的加、解密功能，以及一些基本的图像处理功能。(A kind of image encryption technology based on Arnold transform, and use Matlab GUI interface to design a Arnold encryption algorithm. This program implements the encryption and decryption function of Arnold image encryption algorithm and some basic image processing functions.)

人体脑信号波形检测与分析,包含自相关,功率谱分析的方法(Human brain signal detection and analysis, including autocorrelation, the method of power spectrum analysis)

超像素实现图像分割，可以实现彩色图像分割(An EM algorithm is used for image segmentation.)

存取图像字段 数字图像的存取 将图像转化为数字信息(Access image field )

水表指针识别系统，能够从外部导入任何一个bmp图像，最好是水表图，能够对该图形操作并读出图中水表的度数 (meter target identification system from the outside into any one bmp image, preferably meter map, Graphics to be able to operate and read out the map meter reading)

一个示波器的框架(the framework of an oscilloscope)

此为canny算子的 matlab源代码(This is a canny operator matlab source code)
