README
fcn - Fully Convolutional Networks
==================================
[](https://pypi.python.org/pypi/fcn)
[](https://pypi.org/project/fcn)
[](https://github.com/wkentaro/fcn/actions)
Chainer implementation of [Fully Convolutional Networks](https://github.com/shelhamer/fcn.berkeleyvision.org).
Installation
------------
```bash
pip install fcn
```
Inference
---------
Inference is done as below:
```bash
# forwaring of the networks
img_file=https://farm2.staticflickr.com/1522/26471792680_a485afb024_z_d.jpg
fcn_infer.py --img-files $img_file --gpu -1 -o /tmp # cpu mode
fcn_infer.py --img-files $img_file --gpu 0 -o /tmp # gpu mode
```
Original Image:
Training
--------
```bash
cd examples/voc
./download_datasets.py
./download_models.py
./train_fcn32s.py --gpu 0
# ./train_fcn16s.py --gpu 0
# ./train_fcn8s.py --gpu 0
# ./train_fcn8s_atonce.py --gpu 0
```
The accuracy of original implementation is computed with (`evaluate.py`) after converting the caffe model to chainer one
using `convert_caffe_to_chainermodel.py`.\
You can download vgg16 model from here: [`vgg16_from_caffe.npz`](https://drive.google.com/uc?id=1lKjYpFOc9EAPIt7foOO2nbaOWIpIZRaw).
