Question about eddy detection

[Louis-Bonhomme]

Good afternoon,

I have a question about the condition over the number of pixels in the contour to be identified as an eddy:
the number of pixels is for the surface enclosed by the contour, or is it the number of pixels on the circumference of the contour?

Thank you in advance.

To be exact algorithm count center of pixel in contour.
