W (numpy.ndarray) – Measured frames’ whitefield.
I0 (numpy.ndarray) – Reference image of the sample.
u (numpy.ndarray) – The pixel mapping between the data at the detector’s plane and the reference image at the reference plane.
di (numpy.ndarray) – Sample’s translations along the slow detector axis in pixels.
dj (numpy.ndarray) – Sample’s translations along the fast detector axis in pixels.
ls (float) – Reference image length scale in pixels.

Returns

mse – Average MSE per pixel.
