TIE Phase imaging from defocus stack by Gaussian process regression

This is the MATLAB code for the implementation of neural pupil engineering FPM (NePE-FPM), an optimization framework for FPM reconstruction for off-axis areas.

This is the code for our paper "Analytical phase optical transfer function for Gaussian illumination and the optimized profile"s
