PyTorch implementation of SPN

Soft Proposal Networks for Weakly Supervised Object Localization, ICCV 2017.

[Project Page] [Paper] [Supp]

[Torch code]

Requirements

Conda virtual environment is recommended: conda env create -f environment.yml

• Python3.5
• PyTorch: conda install pytorch torchvision -c soumith
• Packages: torch, torchnet, numpy, tqdm

Usage

1. Clone the SPN repository:

   git clone https://github.com/yeezhu/SPN.pytorch.git

2. Download the backbone model VGG16 (exported from caffe model) and then the model path should be SPN.pytorch/demo/models/VGG16_ImageNet.pt.

3. Install SPN:

   cd SPN.pytorch/spnlib
   bash make.sh

4. Run the training demo:

   cd SPN.pytorch/demo
   bash runme.sh

5. Run the testing demo: EvaluationDemo.ipynb Note: To perform bbox localization on ImageNet, firstly download the SP_GoogleNet_ImageNet model and the annotations into imagenet_eval folder. Extraxt the annotations:

   cd SPN.pytorch/demo/evaluation/imagenet_eval
   tar zxvf ILSVRC2012_bbox_val_v3.tgz

Acknowledgement

In this project, we reimplemented SPN on PyTorch based on wildcat.pytorch. To keep consistency with the Torch version, we use the VGG16 model exported from caffe in fcn.pytorch.
