如何在Google Colab中使用cv2.lipse？

!pip install opencv-python

import cv2

# 创建一个空白图像
image = np.zeros((512, 512, 3), np.uint8)

# 定义椭圆的参数
center_coordinates = (256, 256)
axes_length = (100, 200)
angle = 0
start_angle = 0
end_angle = 360
color = (0, 255, 0)
thickness = 2

# 在图像上绘制椭圆
image = cv2.ellipse(image, center_coordinates, axes_length, angle, start_angle, end_angle, color, thickness)

# 显示图像
plt.imshow(image)
plt.axis('off')
plt.show()
