1.服饰和膨胀
opencv 腐蚀通过cv2.erode实现,膨胀通过cv2.dilate实现,看一下下面代码:
from ctypes.wintypes import SIZE
from multiprocessing.pool import IMapUnorderedIterator
import cv2
import copy
import math
import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np
import os
path=r'D:\learn\photo\cv\dige.png'
img=cv2.imread(path)
def cv_show(name,img):
cv2.imshow(name,img)
#cv2.waitKey(0),接收0,表示窗口暂停
cv2.waitKey(0)
#销毁所有窗口
cv2.destroyAllWindows()
#cv_show('img',img)
kernel=np.ones((3,3),np.uint8)
dila_img=cv2.dilate(img,kernel=kernel,iterations=1)
#cv_show('dila_img',dila_img)
kernel=np.ones((3,3),np.uint8)
ero_img=cv2.erode(img,kernel=kernel,iterations=1)
#cv_show('dila_img',ero_img)
plt.figure(figsize=(400,600))
plt.subplot(131)
plt.imshow(img)
plt.title('img')
plt.subplot(132)
plt.imshow(dila_img)
plt.title('dila_img')
plt.subplot(133)
plt.imshow(ero_img)
plt.title('ero_img')
plt.show()
os.system("pause")
运行结果如下:
