Adaptive step-size strategy for fourier ptychrography microscopy

[code download]MATLAB source code to implement the adaptive step size strategy for Fourier ptychographicreconstruction. A noisy experimental FPM dataset of an USAF resolution target is also included.



Fast Discrete Cosine Transform (DCT)-based TIE solver

[code download] MATLAB source code for implementing the DCT-based TIE solving. Note that an rectangular aperture needs to be used to generate boundary signal that is required for artifacts-free phase retrieval. If the aperture is not rectangular, an iterative DCT solver needs to be used, which can also be downloaded here [code download].



Optimum derivative estimation using Savitzky-Golay differentiation filter

[code download]MATLAB source code for the OSF with the simulated dataset. Note in the simulation, a pure phase object is assumed (single step inverse Laplacian), if one want to retrieve the phase of an absorbing object, then two step-TIE solver based on FFT or DCT should be used instead to get better accuracy.
