RadialSymmetryLikelihood is a set of Matlab routines to compute a coefficient of radial symmetry, i.e., amount of radial symmetry, in grayscale images.

Dependencies

This software requires the Bioformats MATLAB Toolbox.

1. Download it from http://downloads.openmicroscopy.org/bio-formats/5.3.4/

2. Place the toolbox in the same folder where this software is located.

3. Add the Bioformats MATLAB Toolbox to Matlab's path.
For example, if the Bioformats folder is 'bfmatlab', add it to the path by executing...

    addpath(genpath('bfmatlab'))

...in Matlab's command line.

Usage

The main function is radialSymmetryLikelihood.m

There are two main scripts that can be executed from Matlab's prompt:

runSingleRadialSymmetryLikelihood

computes radialSymmetryLikelihood on a single image file
outputs:
1. a .tif image of the accumulator space will be saved
   in the same folder of the input, with '_AccSpace' added to the name
2. two values will be displayed on Matlab's prompt (command line):
   > radial symmery likelihood
   > row and column of global maximum of the accumulator space

Any of the images in the provided folder SampleImages can be used to test this routine.

runMultipleRadialSymmetryLikelihood

computes radialSymmetryLikelihood on all images in a folder;
folder should contain only images to be analized, and nothing else,
    except for the files generated (_AccSpace images and Results.csv)
that is, the program will not read _AccSpace images and Results.csv,
    but will try reading everything else in the folder
outputs:
1. for every image in 'folderpath', a .tif image with the accumulator
   space will be saved in the folder, with '_AccSpace' added to the name
2. a table with resuls will be saved in Results.csv;
   Columns are: name of file, radial symmetry likelihood, row of global maximum,
   column of global maximum

The provided folder SampleImages can be used to test this routine.
