Axon Segmentation Research

We implement deep neural nets for instance-based segmentation of axons in TEM images. Our approach studying segmentation of unmyelinated fibers recently published in [1].

Data associated with this study, were collected as part of the Stimulating Peripheral Activity to Relieve Conditions (SPARC) program and are available through the SPARC Portal (RRID: SCR_017041) under a CC-BY 4.0 license.

All training, testing, and evaluation scripts are hosted in this GitHub repository. Due to large file sizes pretrained models cannot be included in the GitHub package and have to be downloaded from the following link.
