简易验证码图片内容破解

最近新招的实习生妹子，弄的一个 验证码破解脚本， 据说准确率80% 。       自己已经很少写代码了，就直接贴上实习生MM的脚本

        img = Image.open(image)
#       img = img.resize((256,256))   					   ##标准化图片大小
		  ###修改RGB三个通道参数去除干扰线并转为黑白     
        pixdata = img.load()
        for y in range(img.size[1]):
             for x in range(img.size[0]):
                if pixdata[x, y][0] > num:
                    pixdata[x, y] = (0, 0, 0)
        for y in range(img.size[1]):
             for x in range(img.size[0]):
                if pixdata[x, y][1] < 50:
                    pixdata[x, y] = (255, 255, 255)      
        for y in range(img.size[1]):
             for x in range(img.size[0]):
                if pixdata[x, y][2] < num:
                    pixdata[x, y] = (0, 0, 0)
#                else: pixdata[x, y] = (255, 255, 255)

        ###通过高斯模糊、边缘增强、平滑等去除干扰点
        img = img.filter(ImageFilter.GaussianBlur(radius = 1)) 
        img = img.filter(ImageFilter.EDGE_ENHANCE) 
#        img = img.filter(ImageFilter.GaussianBlur(radius = 1)) 
#        img = img.filter(ImageFilter.EDGE_ENHANCE) 
        img = img.filter(ImageFilter.SMOOTH) 
 #       plt.imshow(img)
        ##若此时的图片文字之间还有线相连，或者干扰点较多，则无法识别，可以修改上面的参数，或者刷新验证码重新识别
