image_vortices_coordinates(phase_image, mask=None)

Find the coordinates of phase vortices inside a phase image by computing the winding number directly.

Parameters:

• phase_image (array_like) – Image to detect winding number upon.

• mask (array_like OR None) – Boolean mask to determine coordinates at.

Returns:

The coordinates and winding number of each coordinate.

Return type:

coordinates, weights
