It may well be that those two functions use opposite directions for theta. Do you mind filing an issue? Thanks Stéfan On Fri, Apr 28, 2017, at 11:02, Surya Kasturi wrote:
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
