Hi,

I’m trying to use skimage.measure.EllipseModel to estimate an ellipse around a contour. The results seems to be not so satisfying. I am wondering if I am using “orientation” parameter correctly.

Could anyone please let me know whether “theta” is in radians or degrees? / I am doing anything wrong?

from skimage.measure import EllipseModel

# create ellipse model

ellipse = EllipseModel()

ellipse.estimate(cnt)

xc, yc, a, b, theta = np.array(ellipse.params, dtype=int)

# find perimeter

rr, cc = draw.ellipse_perimeter(xc, yc, a, b, orientation=theta)

# plot

ax.scatter(cc, rr, s=5, label="EllipseModel”)

Thank you,

Surya
