## What it is
A MATLAB re-implementation of Faster R-CNN, a deep-learning object detection framework combining a Region Proposal Network with a detection network that shares convolutional features. It is the original reference code accompanying the 2015 paper, built on a bundled Caffe, and is now deprecated in favor of Detectron.

## Use cases
- train an object detection model on Pascal VOC
- run real-time object detection with region proposal networks
- reproduce Faster R-CNN paper results
- study the original Faster R-CNN MATLAB implementation
- detect objects in images using VGG-16 or ZF networks

## When to choose
- you need the original reference implementation for research reproduction
- you must work in MATLAB with the bundled Caffe build
- you want to study how RPN and detection networks share convolutional layers

## When to avoid
- you want actively maintained object detection tooling - use Detectron or Detectron2 instead
- you prefer Python - use py-faster-rcnn or modern PyTorch detection libraries
- you need recent CUDA/GPU hardware support or modern MATLAB versions

## Facets
- artifact type: library
