  • 发票去章

    前段时间看到了一个发票去红章的博客,看了一下源码将源码 c++改成 python

    感谢博主提供的思路和代码

    原博客https://www.cnblogs.com/skyfsm/p/7638301.html

    ubuntu+python2.7

    #-*- coding: utf-8 -*-
    import cv2
    import numpy as np
    from matplotlib import pyplot as plt
    
    def RemoveRed(img):
        #img = cv2.imread('10.jpg')
        b, g, r = cv2.split(img)
        cv2.imshow('2',r)
        img = cv2.cvtColor(img, cv2.COLOR_RGB2GRAY)#灰度
        th = 180   #阈值
        #cv2.threshold(img, th, 255, 0, img)#二值
        cv2.threshold(r, th, 255, 0, img)
        cv2.imshow('1',img)
        cv2.waitKey()
    
    if __name__ == '__main__':
        img = cv2.imread('10.jpg')
        result = RemoveRed(img)
