README
# fast-rcnn has been deprecated. Please see [Detectron](https://github.com/facebookresearch/Detectron), which includes an implementation of [Mask R-CNN](https://arxiv.org/abs/1703.06870).
### This code base is no longer maintained and exists as a historical artifact to supplement my ICCV 2015 paper. For more recent work that's faster and more accurrate, please see [Faster R-CNN](https://github.com/rbgirshick/py-faster-rcnn) (which also includes functionality for training Fast R-CNN).
# *Fast* R-CNN: Fast Region-based Convolutional Networks for object detection
Created by Ross Girshick at Microsoft Research, Redmond.
### Introduction
**Fast R-CNN** is a fast framework for object detection with deep ConvNets. Fast R-CNN
- trains state-of-the-art models, like VGG16, 9x faster than traditional R-CNN and 3x faster than SPPnet,
- runs 200x faster than R-CNN and 10x faster than SPPnet at test-time,
- has a significantly higher mAP on PASCAL VOC than both R-CNN and SPPnet,
- and is written in Python and C++/Caffe.Fast R-CNN was initially described in an [arXiv tech report](http://arxiv.org/abs/1504.08083) and later published at ICCV 2015.

6. [Usage](#usage)
7. [Extra downloads](#extra-downloads)### Requirements: software
1. Requirements for `Caffe` and `pycaffe` (see: [Caffe installation instructions](http://caffe.berkeleyvision.org/installation.html))
**Note:** Caffe *must* be built with support for Python layers!
```make
# In your Makefile.config, make sure to have this line uncommented
WITH_PYTHON_LAYER := 1
```You can download my [Makefile.config](https://dl.dropboxusercontent.com/s/6joa55k64xo2h68/Makefile.config?dl=0) for reference.
2. Python packages you might not have: `cython`, `python-opencv`, `easydict`
3. [optional] MATLAB (required for PASCAL VOC evaluation only)### Requirements: hardware
1. For training smaller networks (CaffeNet, VGG_CNN_M_1024) a good GPU (e.g., Titan, K20, K40, ...) with at least 3G of memory suffices
2. For training with VGG16, you'll need a K40 (~11G of memory)### Installation (sufficient for the demo)
1. Clone the Fast R-CNN repository
```Shell
# Make sure to clone with --recursive
git clone --recursive https://github.com/rbgirshick/fast-rcnn.git
```
2. We'll call the directory that you cloned Fast R-CNN into `FRCN_ROOT`*Ignore notes 1 and 2 if you followed step 1 above.*
**Note 1:** If you didn't clone Fast R-CNN with the `--recursive` flag, then you'll need to manually clone the `caffe-fast-rcnn` submodule:
```Shell
git submodule update --init --recursive
```
**Note 2:** The `caffe-fast-rcnn` submodule needs to be on the `fast-rcnn` branch (or equivalent detached state). This will happen automatically *if you follow these instructions*.3. Build the Cython modules
```Shell
cd $FRCN_ROOT/lib
make
```
4. Build Caffe and pycaffe
```Shell
cd $FRCN_ROOT/caffe-fast-rcnn
# Now follow the Caffe installation instructions here:
# http://caffe.berkeleyvision.org/installation.html# If you're experienced with Caffe and have all of the requirements installed
# and your Makefile.config in place, then simply do:
make -j8 && make pycaffe
```
5. Download pre-computed Fast R-CNN detectors
```Shell
cd $FRCN_ROOT
./data/scripts/fetch_fast_rcnn_models.sh
```This will populate the `$FRCN_ROOT/data` folder with `fast_rcnn_models`. See `data/README.md` for details.
### Demo
*After successfully completing [basic installation](#installation-sufficient-for-the-demo)*, you'll be ready to run the demo.
**Python**
To run the demo
```Shell
cd $FRCN_ROOT
./tools/demo.py
```
The demo performs detection using a VGG16 network trained for detection on PASCAL VOC 2007. The object proposals are pre-computed in order to reduce installation requirements.**Note:** If the demo crashes Caffe because your GPU doesn't have enough memory, try running the demo with a small network, e.g., `./tools/demo.py --net caffenet` or with `--net vgg_cnn_m_1024`. Or run in CPU mode `./tools/demo.py --cpu`. Type `./tools/demo.py -h` for usage.
**MATLAB**
There's also a *basic* MATLAB demo, though it's missing some minor bells and whistles compared to the Python version.
```Shell
cd $FRCN_ROOT/matlab
matlab # wait for matlab to start...# At the matlab prompt, run the script:
>> fast_rcnn_demo
```Fast R-CNN training is implemented in Python only, but test-time detection functionality also exists in MATLAB.
See `matlab/fast_rcnn_demo.m` and `matlab/fast_rcnn_im_detect.m` for details.**Computing object proposals**
The demo uses pre-computed selective search proposals computed with [this code](https://github.com/rbgirshick/rcnn/blob/master/selective_search/selective_search_boxes.m).
If you'd like to compute proposals on your own images, there are many options.
Here are some pointers; if you run into trouble using these resources please direct questions to the respective authors.1. Selective Search: [original matlab code](http://disi.unitn.it/~uijlings/MyHomepage/index.php#page=projects1), [python wrapper](https://github.com/sergeyk/selective_search_ijcv_with_python)
2. EdgeBoxes: [matlab code](https://github.com/pdollar/edges)
3. GOP and LPO: [python code](http://www.philkr.net/)
4. MCG: [matlab code](http://www.eecs.berkeley.edu/Research/Projects/CS/vision/grouping/mcg/)
5. RIGOR: [matlab code](http://cpl.cc.gatech.edu/projects/RIGOR/)Apologies if I've left your method off this list. Feel free to contact me and ask for it to be included.
### Beyond the demo: installation for training and testing models
1. Download the training, validation, test data and VOCdevkit```Shell
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtrainval_06-Nov-2007.tar
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtest_06-Nov-2007.tar
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCdevkit_08-Jun-2007.tar
```
2. Extract all of these tars into one directory named `VOCdevkit````Shell
tar xvf VOCtrainval_06-Nov-2007.tar
tar xvf VOCtest_06-Nov-2007.tar
tar xvf VOCdevkit_08-Jun-2007.tar
```3. It should have this basic structure
```Shell
$VOCdevkit/ # development kit
$VOCdevkit/VOCcode/ # VOC utility code
$VOCdevkit/VOC2007 # image sets, annotations, etc.
# ... and several other directories ...
```
4. Create symlinks for the PASCAL VOC dataset```Shell
cd $FRCN_ROOT/data
ln -s $VOCdevkit VOCdevkit2007
```
Using symlinks is a good idea because you will likely want to share the same PASCAL dataset installation between multiple projects.
5. [Optional] follow similar steps to get PASCAL VOC 2010 and 2012
6. Follow the next sections to download pre-computed object proposals and pre-trained ImageNet models### Download pre-computed Selective Search object proposals
Pre-computed selective search boxes can also be downloaded for VOC2007 and VOC2012.
```Shell
cd $FRCN_ROOT
./data/scripts/fetch_selective_search_data.sh
```This will populate the `$FRCN_ROOT/data` folder with `selective_selective_data`.
### Download pre-trained ImageNet models
Pre-trained ImageNet models can be downloaded for the three networks described in the paper: CaffeNet (model **S**), VGG_CNN_M_1024 (model **M**), and VGG16 (model **L**).
```Shell
cd $FRCN_ROOT
./data/scripts/fetch_imagenet_models.sh
```
These models are all available in the [Caffe Model Zoo](https://github.com/BVLC/caffe/wiki/Model-Zoo), but are provided here for your convenience.### Usage
**Train** a Fast R-CNN detector. For example, train a VGG16 network on VOC 2007 trainval:
```Shell
./tools/train_net.py --gpu 0 --solver models/VGG16/solver.prototxt \
--weights data/imagenet_models/VGG16.v2.caffemodel
```If you see this error
```
EnvironmentError: MATLAB command 'matlab' not found. Please add 'matlab' to your PATH.
```then you need to make sure the `matlab` binary is in your `$PATH`. MATLAB is currently required for PASCAL VOC evaluation.
**Test** a Fast R-CNN detector. For example, test the VGG 16 network on VOC 2007 test:
```Shell
./tools/test_net.py --gpu 1 --def models/VGG16/test.prototxt \
--net output/default/voc_2007_trainval/vgg16_fast_rcnn_iter_40000.caffemodel
```Test output is written underneath `$FRCN_ROOT/output`.
**Compress** a Fast R-CNN model using truncated SVD on the fully-connected layers:
```Shell
./tools/compress_net.py --def models/VGG16/test.prototxt \
--def-svd models/VGG16/compressed/test.prototxt \
--net output/default/voc_2007_trainval/vgg16_fast_rcnn_iter_40000.caffemodel
# Test the model you just compressed
./tools/test_net.py --gpu 0 --def models/VGG16/compressed/test.prototxt \
--net output/default/voc_2007_trainval/vgg16_fast_rcnn_iter_40000_svd_fc6_1024_fc7_256.caffemodel
```### Experiment scripts
Scripts to reproduce the experiments in the paper (*up to stochastic variation*) are provided in `$FRCN_ROOT/experiments/scripts`. Log files for experiments are located in `experiments/logs`.**Note:** Until recently (commit a566e39), the RNG seed for Caffe was not fixed during training. Now it's fixed, unless `train_net.py` is called with the `--rand` flag.
Results generated before this commit will have some stochastic variation.### Extra downloads
