Hello, everyone, Are the 'Centroid' attributes obtained by the 'regionprops' function the origins of the ellipses? Or how can I get the origins of the ellipses? Thank you very much.

What ellipses are you referring to? Are the objects in your image ellipses, or are you trying to fit them with ellipses? And what is meant by their "origin"? Do you mean their centers?

The objects are in my image ellipses. Yes, the centres of the ellipses.

Ellipses (actual ones) are always symmetric along both the major and minor axes, so they have a well defined origin which is at their centroid.
If you have partial ellipses instead of full ellipses then the centroid of the region will not generally match the origin of the ellipse.
