**均值滤波**

*图像均值滤波
    read_image (Image, 'claudia')
    get_image_size (Image, Width, Height)
    dev_close_window ()
    dev_open_window_fit_size (0, 0, Width, Width, -1, -1, WindowHandle)
    dev_display (Image)
    
    *生成高斯噪声
    gauss_distribution (20, Distribution)
    add_noise_distribution (Image, ImageNoise, Distribution)
    dump_window (WindowHandle, 'bmp', 'D:1/gauss_image')
    mean_image (ImageNoise, ImageMean, 5, 5)
    dump_window (WindowHandle, 'bmp', 'D:1/mean_image')

**函数：高斯噪声gauss\_distribution (20, Distribution)  
均值滤波mean\_image (ImageNoise, ImageMean, 5, 5)**

**中值滤波**

*图像中值滤波
    read_image (Image, 'claudia')
    get_image_size (Image, Width, Height)
    dev_close_window ()
    dev_open_window_fit_size (0, 0, Width, Width, -1, -1, WindowHandle)
    dev_display (Image)
    
    *椒盐噪声分布
    sp_distribution (5, 5, Distribution)
    add_noise_distribution (Image, ImageNoise, Distribution)
    dump_window (WindowHandle, 'bmp', 'D:1/sp_image')
    
    *3x3
    median_image (ImageNoise, ImageMedian, 'square', 3, 'mirrored')
    dump_window (WindowHandle, 'bmp', 'D:1/3_image')
    
    *5x5
    median_image (ImageNoise, ImageMedian, 'square', 5, 'mirrored')
    dump_window (WindowHandle, 'bmp', 'D:1/5_image')
    
    *7x7
    median_image (ImageNoise, ImageMedian, 'square', 7, 'mirrored')
    dump_window (WindowHandle, 'bmp', 'D:1/7_image')

**函数：median\_image (ImageNoise, ImageMedian, ‘square’, 7, ‘mirrored’)**

**square为掩膜类型，可以选择圆形，矩形，线性等。**
