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 [email protected]: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

-Bird
   └── Data
         └─── tfrecords
         └─── images.txt
         └─── image_class_labels.txt
         └─── train_test_split.txt
         └─── images
                 └─── ****.jpg

$ python convert_data.py --dataset_name=Bird --dataset_dir=./Bird/Data

-Car
