===== Introduction =====
This free code is an ImageJ plugin that allows detect the neuronal structure from image.

This plugin, is a joint work between the team [[http://spineup.jimdo.com/|"Structural Synaptic Plasticity"]] of SpineUp and [[https://esus.unirioja.es/psycotrip/|"Programming and Symbolic Computation Team”]] of University of La Rioja.

===== Description =====

This plugin implement a method to detect the neuronal structure from image (in the example, images of hippocampal neuron in culture, transfected with Actin-GFP).

This method can be split into two steps, the first one process the image with filters to dismiss the elements which are not part of the structure of the main neuron, and the second one is based in the persistent homology. This is a technique which allows one to study the lifetimes of topological attributes.
