cv2.fitEllips

I'm sorry, but there is no `cv2.fitEllips` function in the OpenCV library. Perhaps you meant `cv2.fitEllipse`, which fits an ellipse to a set of points in an image? This function takes in a `numpy` array of points, and returns an `((x,y), (MA,ma), angle)` tuple which represents the center of the ellipse, the lengths of the major and minor axes, and the angle of rotation of the ellipse. Here's an example usage:

import cv2
import numpy as np

# Generate some random points
points = np.random.randint(0, 100, (50, 2))

# Fit an ellipse to the points
ellipse = cv2.fitEllipse(points)

# Draw the ellipse on a black image
img = np.zeros((100, 100, 3), dtype=np.uint8)
cv2.ellipse(img, ellipse, (0, 255, 0), 2)

# Display the result
cv2.imshow("Image", img)
cv2.waitKey(0)
cv2.destroyAllWindows()
