Feature Pyramid Network on caffe
This is the unoffical version Feature Pyramid Network for Feature Pyramid Networks for Object Detection https://arxiv.org/abs/1612.03144
FPN(resnet50)-end2end result is implemented without OHEM and train with pascal voc 2007 + 2012 test on 2007

the red and yellow are shared params
In the paper the anchor setting is Ratios: [0.5,1,2],scales :[8,]
With the setting and P2~P6, all anchor sizes are [32,64,128,512,1024]
,but this setting is suit for COCO dataset which has so many small targets.
But the voc dataset targets are range [128,256,512]
.
So, we desgin the anchor setting:Ratios: [0.5,1,2],scales :[8,16]
, this is very import for voc dataset.
download voc07,12 dataset ResNet50.caffemodel
and rename to ResNet50.v2.caffemodel
cp ResNet50.v2.caffemodel data/pretrained_model/

In my expriments, the codes require ~10G GPU memory in training and ~6G in testing. your can design the suit image size, mimbatch size and rcnn batch size for your GPUS.
cd caffe-fpn
mkdir build
cd build
cmake ..
make -j16 all

0 1 is GPU id.
- all tests passed
- evaluate object detection performance on voc
- evaluate merged rcnn version performance on voc
