Detectron

Detectron is Facebook AI Research's software system that implements state-of-the-art object detection algorithms, including Mask R-CNN. It is written in Python and powered by the Caffe2 deep learning framework.

At FAIR, Detectron has enabled numerous research projects, including: Feature Pyramid Networks for Object Detection, Mask R-CNN, Detecting and Recognizing Human-Object Interactions, Focal Loss for Dense Object Detection, Non-local Neural Networks, Learning to Segment Every Thing, and Data Distillation: Towards Omni-Supervised Learning.

Example Mask R-CNN output.

Introduction

The goal of Detectron is to provide a high-quality, high-performance codebase for object detection research. It is designed to be flexible in order to support rapid implementation and evaluation of novel research. Detectron includes implementations of the following object detection algorithms:

Mask R-CNN -- Marr Prize at ICCV 2017
RetinaNet -- Best Student Paper Award at ICCV 2017
Faster R-CNN
RPN
Fast R-CNN
R-FCN

using the following backbone network architectures:

ResNeXt{50,101,152}
ResNet{50,101,152}
Feature Pyramid Networks (with ResNet/ResNeXt)
VGG16

Additional backbone architectures may be easily implemented. For more details about these models, please see References below.
