数字识别基于MATLAB的数字识别系统的研究与实现(Digital Identification)

数字图像在产生过程中经常会受到噪音污染。因此，对于数字图像应该对其进行去噪音处理。在传统的基于傅里叶变换的信号去噪音方法中，可以使得信号和噪音的频带重叠部分尽可能的小，这样就可以在频域通过时，不需改变滤波方法而将信号和噪音分隔开来。但是，如果信号和噪音的频域重合时，用该方法进行噪音处理的效果就比较差。(digital image in the selection process will be subject to regular noise pollution. Therefore, the digital image should be carried out to deal with the noise. Based on the traditional Fourier Transform method of signal to noise, can result in a signal and noise bands overlap small as possible, so it can be adopted in the frequency domain, the need to change methods of filtering the signal and noise to separate. However, if the signal and noise in the frequency domain coincidence, the method for dealing with the effects of noise on the relatively poor.)

此函数是进行串并变化的功能函数，包含两个文件，一个进行提取基数为一个提取偶数位，从而达到串并变换的目的。这是在做需要多路进行数字调制所需要的步骤(This function is built to transform a sequence to serial and parallel sequence)

这个工程实现了红绿蓝三个分量的提取，采用了新的方法，比传统的方法要清楚些，并且对红色分量做了DFT变换，用模版来对图像进行加密，为图像加密提供了一种新的思路。代码免费下载，功能优。(The project implements the extraction of three components red, green and blue, using a new method to make it clear than the more traditional methods, and components made of red DFT transform, the image used to encrypt the template for the image encryption provides a kinds of new ideas. Code free download, features excellent.)
