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")
