利用opencv进行腐蚀和膨胀操作

import cv2
import numpy as np
# 读取图片
image = cv2.imread(r"E:\ToothFairy_Dataset\res\p5\244.png", cv2.IMREAD_UNCHANGED)
# 设置卷积核
kernel = np.ones((5, 5), np.uint8)
down=np.ones((3, 3), np.uint8)
# 图像膨胀处理
result = cv2.dilate(image, kernel)
# 图像腐蚀处理
erosion = cv2.erode(result, down)
# 显示窗口
cv2.imshow("erosion", erosion)
cv2.imshow("result", result)
cv2.imshow("image", image)

# 窗口等待
cv2.waitKey(0)
cv2.destroyAllWindows()
