Python实现图像的垂直投影示例

Python + OpenCV 直接上代码 import cv2 import numpy as np from matplotlib import pyplot as plt from PIL import Image img=cv2.imread('0002.jpg') #读取图片,装换为可运算的数组 GrayImage=cv2.cvtColor(img,cv2.COLOR_BGR2GRAY) #将BGR图转为灰度图 ret,thresh1=cv2.threshold(GrayImage,130,255,cv2.THRESH_BINARY) #将图片进行二值化(130,255)之间的点
