- This is an implementation of Pose Proposal Networks with Chainer including training and prediction tools.

- Prior to training, let's download dataset. You can train with MPII or COCO dataset by yourself.
- For simplicity, we will use docker image of idein/chainer which includes Chainer, ChainerCV and other utilities with CUDA driver. This will save time setting development environment.
- If you train with COCO dataset you can skip.
- Access MPII Human Pose Dataset and jump to
Download
page. Then download and extract bothImages (12.9 GB)
andAnnotations (12.5 MB)
.
We need decode mpii_human_pose_v1_u12_1.mat
to generate mpii.json
. This will be used on training or evaluating test dataset of MPII.
$ sudo docker run --rm -v $(pwd):/work -v path/to/dataset:/data -w /work idein/chainer:4.5.0 python3 convert_mpii_dataset.py /data/mpii_human_pose_v1_u12_2/mpii_human_pose_v1_u12_1.mat /data/mpii.json
It will generate mpii.json
at path/to/dataset
where is the root directory of MPII dataset. For those who hesitate to use Docker, you may edit config.ini
as necessary.
- If you train with MPII dataset you can skip.
- Access COCO dataset and jump to
Dataset
->download
. Then download and extract2017 Train images [118K/18GB]
,2017 Val images [5K/1GB]
and2017 Train/Val annotations [241MB]
.
$ sudo docker run --rm -v $(pwd):/work -v path/to/dataset:/data -w /work idein/chainer:4.5.0 python3 train.py
- Optional argument
--runtime=nvidia
maybe require for some environment. - This will train a model the base network is MobileNetV2 with MPII dataset located in
path/to/dataset
on host machine. - If we would like to train with COCO dataset, edit a part of
config.ini
as follow:
before
# parts of config.ini
[dataset]
type = mpii
after
# parts of config.ini
[dataset]
type = coco
- We can choice ResNet based network as the original paper adopts. Edit a part of
config.ini
as follow:
before
[model_param]
model_name = mv2
after
[model_param]
# you may also choice resnet34 and resnet50
model_name = resnet18
- Very easy, all we have to do is:
$ sudo docker run --rm -v $(pwd):/work -v path/to/dataset:/data -w /work idein/chainer:4.5.0 python3 predict.py
We tested on an Ubuntu 16.04 machine with GPU GTX1080(Ti)
We will build OpenCV from source to visualize the result on GUI.
$ cd docker/gpu
$ cat build.sh
docker build -t ppn .
$ sudo bash build.sh
-
Set your USB camera that can recognize from OpenCV.
-
Run
video.py
$ python video.py
or
$ sudo bash run_video.sh
- To use feature of Static Subgraph Optimizations to accelerate inference speed, we should install Chainer 5.0.0 and CuPy 5.0.0 .
- Prepare high performance USB camera so that takes more than 60 FPS.
- Run
high_speed.py
instead ofvideo.py
- Do not fall from the chair with surprise :D.
- Implementation of Pose Proposal Networks (NotePC with e-GPU)
- Demo: Pose Proposal Network on a Raspberry Pi
- It runs on Raspberry Pi 3 locally using its GPU (VideoCore IV) with almost 10 FPS.
- It also runs on Raspberry Pi Zero with 6.6 FPS.
