补充资料：
https://github.com/rbgirshick/fast-rcnn
this code base is no longer maintained and exists as a historical artifact to supplement my iccv 2015 paper.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 (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 and later published at iccv 2015.
license
fast r-cnn is released under the mit license (refer to the license file for details).

if you find fast r-cnn useful in your research, please consider citing:

requirements: software requirements: hardware basic installation demo beyond the demo: training and testing usage extra downloadsrequirements: software
requirements for caffe and pycaffe (see: caffe installation instructions)note: caffe must be built with support for python layers!# in your makefile.config, make sure to have this line uncommented with_python_layer := 1you can download my makefile.config for reference. python packages you might not have: cython, python-opencv, easydict [optional] matlab (required for pascal voc evaluation only)requirements: hardware
for training smaller networks (caffenet, vgg_cnn_m_1024) a good gpu (e.g., titan, k20, k40, ...) with at least 3g of memory suffices for training with vgg16, you'll need a k40 (~11g of memory)installation (sufficient for the demo)
clone the fast r-cnn repository# make sure to clone with --recursive git clone --recursive https://github.com/rbgirshick/fast-rcnn.gitwe'll call the directory that you cloned fast r-cnn into frcn_rootignore 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:git submodule update --init --recursivenote 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.build the cython modulescd $frcn_root/lib makebuild caffe and pycaffecd $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 pycaffedownload pre-computed fast r-cnn detectorscd $frcn_root ./data/scripts/fetch_fast_rcnn_models.shthis will populate the $frcn_root/data folder with fast_rcnn_models. see data/readme.md for details.demo
after successfully completing basic installation, you’ll be ready to run the demo.
python
to run the demo
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.
cd $frcn_root/matlab
matlab # wait for matlab to start…
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. 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.
selective search: original matlab code, python wrapper edgeboxes: matlab code gop and lpo: python code mcg: matlab code rigor: matlab codeapologies 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
download pre-computed selective search object proposals
pre-computed selective search boxes can also be downloaded for voc2007 and voc2012.
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).
cd $frcn_root
./data/scripts/fetch_imagenet_models.sh
these models are all available in the caffe 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:
./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:
./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:
./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
./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.
