WebbWe will use two approaches: Segment the fiducial using a thresholding approach, derive the sphere's radius from the segmentation. This approach is solely based on SimpleITK. Localize the fiducial's edges using the Canny edge detector and then fit a sphere to these edges using a least squares approach.
