说明：  P1口的8个灯循环亮，按P32后全部闪烁5次后继续循环亮， 中断程序的典型应用。 (P1 mouth of the eight bright light cycles, according to P32, all the flashes five times after the continued cycle of light, interrupt procedures typical application.)

说明：  用matlab实现的肤色检测，采用CbCr椭圆聚类算法，克服了高光的干扰，能很好的把肤色分割出来。(Skin color detection using matlab implementation, using CbCr elliptical clustering algorithm, to overcome the interference of high light, the color can be a good split.)

Wavelet denoising For using this code need to use signal toolbox and general toolbox in your matlab In the first part of this assignment, we asked to obtain a (black-and-white) digital image of size 512 by 512 and then generate noisy image by adding a Gaussian noise but under the condition of having SNR=20dB by select the suitable value of variance for Gaussian noise formula. Second step is performing wavelet denoising using the hard thresholding (Use the db 6 for four levels) in the condition of finding the optimal thresholding value of T in terms of the SNR obtained. It means that, we should find the highest SNR value by finding the suitable value for threshold. Then we asked to do the same process but this time using soft thresholding. Finally for the last part of question one, we should compare the results of the obtained SNR with the recommendations of 3*sigma for the hard thresholding and 3/2*sigma for the soft thresholding.

用MATLAB编码不归零码和HDB3码之间的转换的编码部分(MATLAB code is not used and the HDB3 code NRZ coding part of the conversion between)
