Main Results
Note: The reimplemented results are slightly different from those presented in the paper for different training settings, but the conclusions are still consistent. For example, this code doesn't use multi-scale training which should boost the results for both DeRPN and RPN.

( "*": On Pascal VOC dataset, we found that it is more suitable to train the DeRPN+R-FCN model with 900 proposals. For other experiments, we use the default proposal number to train the models, i.e., 2000 proposals fro Faster R-CNN, 300 proposals for R-FCN. )

Getting Started
- Requirements
- Installation
- Preparation for Training & Testing
- Usage
Requirements
- Cuda 8.0 and cudnn 5.1.
- Some python packages: cython, opencv-python, easydict et. al. Simply install them if your system misses these packages.
- Configure the caffe according to your environment (Caffe installation instructions). As the code requires pycaffe, caffe should be built with python layers. In Makefile.config, make sure to uncomment this line:
WITH_PYTHON_LAYER := 1
- An NVIDIA GPU with more than 6GB is required for ResNet-101.
Installation
-
Clone the DeRPN repository
git clone https://github.com/HCIILAB/DeRPN.git -
Build the Cython modules
cd $DeRPN_ROOT/lib make -
Build caffe and pycaffe
cd $DeRPN_ROOT/caffe make -j8 && make pycaffe
Preparation for Training & Testing
Dataset
-
Download the datasets of Pascal VOC 2007 & 2012, MS COCO 2017 and COCO-Text.
-
You need to put these datasets under the $DeRPN_ROOT/data folder (with symlinks).
-
For COCO-Text, the folder structure is as follow:
$DeRPN_ROOT/data/coco_text/images/train2014 $DeRPN_ROOT/data/coco_text/images/val2014 $DeRPN_ROOT/data/coco_text/annotations # train2014, val2014, and annotations are symlinks from /pth_to_coco2014/train2014, # /pth_to_coco2014/val2014 and /pth_to_coco2014/annotations2014/, respectively. -
For COCO, the folder structure is as follow:
$DeRPN_ROOT/data/coco/images/train2017 $DeRPN_ROOT/data/coco/images/val2017 $DeRPN_ROOT/data/coco/images/test-dev2017 $DeRPN_ROOT/data/coco/annotations # the symlinks are similar to COCO-Text -
For Pascal VOC, the folder structure is as follow:
$DeRPN_ROOT/data/VOCdevkit2007 $DeRPN_ROOT/data/VOCdevkit2012 #VOCdevkit2007 and VOCdevkit2012 are symlinks from $VOCdevkit whcich contains VOC2007 and VOC2012.
Pretrained models
Please download the ImageNet pretrained models (VGG16 and ResNet-101, password: k4z1), and put them under
$DeRPN_ROOT/data/imagenet_models
We also provide the DeRPN pretrained models here (password: fsd8).
Usage
cd $DeRPN_ROOT
./experiments/scripts/faster_rcnn_derpn_end2end.sh [GPU_ID] [NET] [DATASET]
# e.g., ./experiments/scripts/faster_rcnn_derpn_end2end.sh 0 VGG16 coco_text
