For Beginners
-------------

Installation
++++++++++++

.. code-block:: bash

pip install fcn


Forwarding
++++++++++

Forwarding is done as below, and computation graph is `here <https://github.com/wkentaro/fcn/blob/master/_images/fcn8s_forward.jpg>`_.

.. code-block:: bash

# Download sample image

For Developers
--------------


Installation
++++++++++++

.. code-block:: bash

git clone https://github.com/wkentaro/fcn.git
cd fcn

python setup.py install

You need to download pascal VOC2012 dataset from `here <http://host.robots.ox.ac.uk/pascal/VOC/voc2012/>`_,
and install it as below construction::

- fcn - data - pascal - VOC2012 -- JPEGImages
- SegmentationClass
- ...

Fowarding
+++++++++

Forwarding with trained model in caffe is done as below:

.. code-block:: bash

# This downloads caffemodel and convert it to chainermodel
./scripts/caffe_to_chainermodel.py

# forwarding of the networks
./scripts/fcn_forward.py --img-files data/pascal/VOC2012/JPEGImages/2007_000129.jpg

.. image:: https://raw.githubusercontent.com/wkentaro/fcn/master/_images/fcn8s_2007_000129.jpg

Original Image: http://host.robots.ox.ac.uk/pascal/VOC/voc2012/


Training
++++++++

.. code-block:: bash

./scripts/fcn_train.py

Currently we support only training FCN32s.
The learning curve looks like below:

.. image:: https://raw.githubusercontent.com/wkentaro/fcn/master/_images/fcn32s_learning_curve.png

Forwarding with ``fcn32s_60000.chainermodel`` ends with below result:
