DeconvolutionLab2 is freely accessible and opensource for 3D deconvolution microscopy; it can be linked to wellknown imaging software platforms, ImageJ, Fiji, ICY, Matlab, and it runs as a standalone application.
The backbone of our software architecture is a library that contains the numbercrunching elements of the deconvolution task. It includes the tool for a complete validation pipeline. Inquisitive minds inclined to peruse the code will find it fosters the understanding of deconvolution.
At this stage, DeconvolutionLab2 includes a friendly user interface to run the following algortihms: Regularized Inverse Filter, Tikhonov Inverse Filter, Naive Inverse Filter, RichardsonLucy, RichardsonLucy Total Variation, Landweber (Linear Least Squares), Nonnegative Least Squares, BoundedVariable Least Squares, Van Cittert, TikhonovMiller, Iterative Constraint TikhonovMiller, FISTA, ISTA.

Put the DeconvolutionLab_2 into the java folder of Matlab Example of Matlab commands javaaddpath([matlabroot filesep 'java' filesep 'DeconvolutionLab_2.jar']) result = DL2.RIF(rand(40, 40, 30), rand(30, 30, 30), 0.125, 'out mip rand'); 

Standalone application 
Require a Java JDK 1.8 properly installed in the machine. Doubleclick on the DeconvolutionLab_2.jar file to the start the user interface of DeconvolutionLab2.


Java code 
Use the DeconvolutionLab2 as a Java library Snippet of Java code RealSignal r = Lab.getImage("fundus.tif"); RealSignal h = new DirectionalMotionBlur(2, 20, 20).generate(r.nx, r.ny, r.nz); Simulation sim = new Simulation(0, 1, 0); RealSignal y = sim.run(r, h); TikhonovRegularizedInverseFilter trif = new TikhonovRegularizedInverseFilter(0.001); RealSignal x = trif.run(y, h); Lab.show(x, "TRIF " + i);
