Weakly Supervised Data Augmentation Network

This is the official TensorFlow implementation of WS-DAN.

See Better Before Looking Closer: Weakly Supervised Data Augmentation Network for Fine-Grained Visual Classification.

Compatibility

• The code is tested using Tensorflow r1.x under Ubuntu 16.04 with Python 2.x and Python 3.x.

• Recommend Environment: Anaconda

Requirements

$ git clone git@github.com:tau-yihouxiang/WS_DAN.git
$ cd WS_DAN
$ python setup.py install

• opencv, tqdm

$ conda install -c menpo opencv
$ pip install tqdm

Datasets and Pre-trained models

Datasets	#Attention	Pre-trained model
CUB-200-2011	32	WS-DAN
Stanford-Cars	32	WS-DAN
FGVC-Aircraft	32	WS-DAN

Inspiration

The code is based on the Tensorflow-Slim Library.

Preparing Datasets

Download and pre-process images and labels to tfrecords.

The convert_data.py will generate ./tfrecords folder blow the provided $dataset_dir
