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.)

星形16QAM的编码与解码，主要是进码流进行编码，加噪声，显示画图，最后解码(Star 16QAM encoding and decoding, encoding and decoding of the star 16QAM star 16QAM encoding and decoding, encoding and decoding of the star 16QAM, star 16QAM encoding and decoding,)

可以把一段脑电信号分解成多个频段，然后各频段重构就可以提取脑电信号的各频段成份了(Period of EEG can be broken down into multiple bands, each band then refactoring can extract EEG bands ingredients)

Matlab画平滑曲线的两种方法（ 拟合或插值后再用plot即可） 自然状态下，用plot画的是折线，而不是平滑曲线。有两种方法可以画平滑曲线，第一种是拟合的方法，第二种是用spcrv，其实原理应该都一样就是插值。下面是源程序。(You can then use the plot) Natural state, with the plot is a line drawing, instead of a smooth curve. There are two ways to draw a smooth curve, the first one is the fitting method, and the second is to use spcrv, in fact, the same principle should be that the interpolation. Here is the source.)

说明：  基于matlab的图像配准程序，算法使用的是sift原理，配准效果良好(Matlab based image registration procedures, the algorithm uses the principle of SIFT, registration good results)
