You can also find some fancy results and comparisons on my website.

If you are interested in our work, I wrote a #behind_the_paper post for further reading.

Here is also a blog about it for further reading.

This method has been tested on various types of Confocal microscopy & STED microscopy, Wide-field & TIRF microscopy, Light-sheet microscopy, Multi-photon microscopy, and Structured illumination microscopy, feasible for single-slice, time-lapse, and volumetric datasets.

This repository contains the updating version of Sparse deconvolution. The Sparse deconvolution is an universal post-processing framework for fluorescence (or intensity-based) image restoration, including xy (2D), xy-t (2D along t axis), and xy-z (3D) images. It is based on the natural priori knowledge of forward fluorescence imaging model: sparsity and continuity along xy-t (z) axes.
