Description: 下载并读入被噪音污染的Noisychurch图像数据，用Matlab 编程采用下述方法分
别实现该图像的增强操作：
1） 用空域法实现图像的增强，分别采用如下模板操作：2x2 和3x3 的幅值为1
的模板，比较去噪和模糊的折中效果；采用3x3 的中值滤波器进行去噪操作；
采用Laplacian 模板[0 -1 0 -1 5 -1 0 -1 0]进行锐化操作。
2） 用频域法实现该图像的低通和高通滤波，选择合适的截止频率。
3） 用小波分析法实现该图像的低通和高通滤波，注意离散小波分析的分解和重
构算法的运用。
4） 比较上述三种处理方法的结果。 -Download and read by the noise pollution Noisychurch image data using Matlab programming using the following method to achieve the image enhancement operation: 1) image enhancement airspace law, respectively, using the following template operation: 2x2 and 3x3 amplitude a template comparison denoising and fuzzy compromise denoising operation with a 3x3 median filter using Laplacian template [0-10 -15-1 0-10] for sharpening operation. . 2) low-pass and high-pass filtering of the image using the frequency-domain method, select the appropriate cut-off frequency. 3) low-pass and high-pass filtering of the image using wavelet analysis, pay attention to the use of discrete wavelet analysis decomposition and reconstruction algorithm. 4) comparing the results of the three processing method.
