I add in the ability to detect center fiducials that mark the principal point. Thought it might be useful for others! :)
To do so, I updated:
hipp.batch.iter_detect_fiducialsto provide the option "center_fiducial".If "center_fiducial" is True, it calls a new function I created based on the pre-existing hipp functions:
hipp.core.define_center_windowthat defines a window around the center point that is 1/8th of the image height x 1/8th of the image width.
As per the original workflow, the image is sliced by this frame to perform template matching and then creates a dataframe with one column "principal_point" that contains the coordinates of the detected fiducial.
