OpenCV之形态学操作源码

#不用手动创建卷积核 #getStructuringElement(shape, ksize[, anchor]) # shape是指卷积核的形状, 注意不是指长宽, 是指卷积核中1形成的形状. # MORPH_RECT 卷积核中的1是矩形, 常用. # MORPH_ELLIPSE 椭圆 # MORPH_CROSS 十字 import cv2 import numpy as np img = cv2.imread('./test.jpg') kernel_1 = cv2.getStructuringElement(cv2.MORPH_RECT,(5,5)) kernel_2 = cv2.getStructuringElement(cv2.MORPH_ELLIPSE,(5,5)) kernel_3 = cv2.getStructuringElement(cv2.MORPH_CROSS,(5,5)) print(kernel_1) print(kernel_2) print(kernel_3) #腐蚀操作 ; 膨胀换为 cv2.dilate dst_1 = cv2.erode(img,kernel_1,iterations=1) dst_2 = cv2.erode(img,kernel_2) dst_3 = cv2.erode(img,kernel_3) cv2.imshow('img',np.hstack((img,dst_1,dst_2,dst_3))) cv2.waitKey(0) cv2.destroyALLWindows()
