对一会度图片加入高斯噪声和椒盐噪声，并进行中值滤波和均值滤波处理(Degree of a picture will be added Gaussian noise and salt and pepper noise and median filter and mean filter processing)

使用matlab编程实现AR模型中的参数确定(AR model)

This code is used for extracting texture features in an image

说明：  弦位法的计算程序，通过它可以近似在特定区间中的根(String with the calculating process can be approximated by its roots in a specific interval)

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.

create different noise patterns and then use different filtering methods on them.
