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
