+# 知识点： headers反爬，图片验证码，机器学习，图片验证码去噪点
+
+## 解题思路
+
+先来看一下图片验证码，为了提高识别的准确度就需要去掉噪点，用windows的画图工具打开
+
+![请求](./img/1.png)
+
+你会发现大部分噪点的r, g, b值都是0，0，0，也就是黑色
+
+![请求](./img/3.png)
+
+这就好处理了，将黑色部分全部变成白色
+
+    # 将部分像素值变为纯白色
+    if r == 0 and g == 0 and b == 0:
+        img.putpixel((i, j), (255, 255, 255))
+
+在将图片灰度转换，二值化
+
+    img = img.convert('L')
+    pixels = img.load()
+    for x in range(img.width):
+        for y in range(img.height):
+            if pixels[x, y] > standard:
+                pixels[x, y] = 255
+            else:
+                pixels[x, y] = 0
+
+看一下效果图
+
+![请求](./img/1-test.png)
+
+接下来就和18题一样，利用百度ocr进行文字识别
