RON: Reverse Connection with Objectness Prior Networks for Object Detection

RON is a state-of-the-art visual object detection system for efficient object detection framework. The code is modified from py-faster-rcnn. You can use the code to train/evaluate a network for object detection task. For more details, please refer to our CVPR paper.

***There is also a tensorflow re-implementation of RON at RON_Tensorflow, thanks @HiKapok!

RON Installation

Clone the RON repository

git clone https://github.com/taokong/RON.git

Build Caffe and pycaffe

cd $RON_ROOT/
git clone https://github.com/taokong/caffe-ron.git
cd caffe-ron
make -j8 && make pycaffe
*this version use CUDNN for efficiency, so make sure that "USE_CUDNN := 1" in the Makefile.config file.

Build the Cython modules
```
cd $RON_ROOT/lib
make
```

installation for training and testing models on PASCAL VOC dataset

3.0 The PASCAL VOC dataset has the basic structure:

 $VOCdevkit/                           # development kit
 $VOCdevkit/VOCcode/                   # VOC utility code
 $VOCdevkit/VOC2007                    # image sets, annotations, etc.

3.1 Create symlinks for the PASCAL VOC dataset

 cd $RON_ROOT/data
 ln -s $VOCdevkit VOCdevkit2007
 ln -s $VOCdevkit VOCdevkit2012

Test with PASCAL VOC dataset

Now we provide two models for testing the pascal voc 2007 test dataset. To use demo you need to download the pretrained RON model, please download the model manually from BaiduYun(Google Drive), and put it under $data/RON_models.

4.0 The original model as introduced in the RON paper:
```
 ./test_voc07.sh
 # The final result of the model should be 74.2% mAP.
 
```
4.1 A lite model we make some optimization after the original one:
```
 ./test_voc07_reduced.sh
 # The final result of the model should be 74.1% mAP.
```
Train with PASCAL VOC dataset

Please download ImageNet-pre-trained VGG models manually from BaiduYun(Google Drive), and put them into $data/ImageNet_models. Then everything is done, you could train your own model.

5.0 The original model as introduced in the RON paper: 

    ./train_voc.sh
    
5.1 A lite model we make some optimization after the original one:

    ./train_voc_reduced.sh
