A Python reimplementation of the Faster R-CNN object detection model built on a fork of Fast R-CNN and Caffe. The repository is officially deprecated in favor of Detectron and is no longer maintained.

Use cases

• run object detection on images with Faster R-CNN
• train a region proposal network detector in Python
• reproduce NIPS 2015 Faster R-CNN paper experiments
• run the Faster R-CNN demo on pretrained VGG16 models
• study a classic deep learning object detection implementation

When to choose

• you need to reproduce the original Faster R-CNN paper results in Python
• you are studying or extending legacy Caffe-based detection code
• you need approximate joint training for Faster R-CNN on old CUDA toolchains

When to avoid

• you are starting a new object detection project - use Detectron, Detectron2, MMDetection, or torchvision instead
• you need compatibility with MATLAB-trained Faster R-CNN models
• you need modern CUDA/cuDNN support or active maintenance
