FibeR-CNN

This repository demonstrates the deep learning-based analysis of individual, agglomerated, looped and/or occluded fibers. It accompanies the following publication:
FibeR-CNN: Expanding Mask R-CNN to Improve Image-Based Fiber Analysis

The utilized region-based convolutional neural network (R-CNN) was inspired by the Mask R-CNN and Keypoint R-CNN architecture, developed by He et al. and is based on an implementation of Wu et al., realized with PyTorch.

Setup

The setup assumes that you have an Nvidia GPU in your system. However, it should be possible to run the code without a compatible GPU, by adjusting the relevant packages (pytorch and detectron2). As of now, detectron2 does not officially support Windows. However, there have been reports that it can be run on Windows with some tweaks (see this repository and the accompanying tutorial).

Docker

1. Install docker.
2. Install docker-compose.
