image_vortices(phase_image)[source]#

Find the coordinates of phase vortices inside a phase image by computing the winding number directly. The coordinates are returned as an image.

Parameters:

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

Returns:

Image with the integer winding number at each pixel.

Return type:

winding_number
