OpenCV:圖像的開運算與閉運算

導包：

import numpy as np
import cv2
import matplotlib.pyplot as plt
def show(image):
    plt.imshow(image)
    plt.axis('off')
    plt.show()
def imread(image):
    image=cv2.imread(image)
    image=cv2.cvtColor(image,cv2.COLOR_BGR2RGB)
    return image

開運算代碼：

kernel=cv2.getStructuringElement(cv2.MORPH_RECT,(10,10))
opening=cv2.morphologyEx(image,cv2.MORPH_OPEN,kernel)
show(opening)

閉運算代碼：#下面開始閉運算,膨脹以後再腐蝕，用於去除黑點

kernel=cv2.getStructuringElement(cv2.MORPH_RECT,(10,10))
opening=cv2.morphologyEx(image,cv2.MORPH_OPEN,kernel)
show(opening)
