开运算opencv-python

开运算是一种形态学图像处理操作，通过先对图像进行腐蚀，再进行膨胀来实现。它能够排除小团块物体。在OpenCV中，可以使用`cv2.morphologyEx`函数来进行开运算操作。下面是一个示例代码：

import cv2
import numpy as np

img = cv2.imread("./cycle.png", cv2.IMREAD_COLOR)
kernel = np.ones((5, 5), np.uint8)
opening = cv2.morphologyEx(img, cv2.MORPH_OPEN, kernel)

cv2.imshow("opening", opening)
cv2.waitKey(0)
cv2.destroyAllWindows()

运行以上代码，将会展示开运算后的图像。开运算在图像处理中常用于平滑图像、去除噪点和小物体等操作。<em>1</em><em>2</em><em>3</em>
