3D reconstruction framework for light field microscopy

Project description

pyolaf - A Python-based 3D reconstruction framework for light field microscopy

pyolaf is a Python port of the oLaF 3D reconstruction framework for light field microscopy (LFM).

Overview

The light field microscope (LFM) allows for 3D imaging of fluorescent specimens using an array of micro-lenses (MLA) that capture both spatial and directional light field information in a single shot. oLaF is a Matlab framework for 3D reconstruction of LFM data with a deconvolution algorithm that reduces aliasing artifacts.

pyolaf brings these same features to the Python ecosystem, using GPU acceleration and some further code optimizations to speed up deconvolution by 20x.

Limitations

pyolaf only supports regular grids and single-focus conventional light-field microscopes. In particular Fourier LFM, hexagonal grids, and multi-focus lenslets are currently not supported. Pull requests to add these are welcome!
