Visual Relationship Detection with Deep Structural Ranking

The code is written in python and pytorch (0.2.0) [torch-0.2.0.post3].

Since I have graduated, I may not be able to respond to the issues in time. Thanks for your understanding.

Clone the repo

  • git clone git@github.com:GriffinLiang/vrd-dsr.git
  • git submodule update --recursive

OR

  • git clone --recursive git@github.com:GriffinLiang/vrd-dsr.git

Data Preparation

  1. Download VRD Dateset (image, annotation, backup) and put it in the path ~/data. Replace ~/data/sg_dataset/sg_test_images/4392556686_44d71ff5a0_o.gif with ~/data/vrd/4392556686_44d71ff5a0_o.jpg

  2. Download VGG16 trained on ImageNet and put it in the path ~/data

  3. Download the meta data (so_prior.pkl) [Baidu YUN] or [Google Drive] and put it in ~/data/vrd

  4. Download visual genome data (vg.zip) [Baidu YUN] or [Google Drive] and put it in ~/data/vg

  5. Word2vec representations of the subject and object categories are provided in this project. If you want to use the model for novel categories, please refer to this blog.

The folder should be:

├── sg_dataset
│   ├── sg_test_images
│   ├── sg_train_images
│   
├── VGG_imagenet.npy
└── vrd
    ├── gt.mat
    ├── obj.txt
    ├── params_emb.pkl
    ├── proposal.pkl
    ├── rel.txt
    ├── so_prior.pkl
    ├── test.pkl
    ├── train.pkl
    └── zeroShot.mat

Data format

  • train.pkl or test.pkl

    • python list
    • each item is a dictionary with the following keys: {'img_path', 'classes', 'boxes', 'ix1', 'ix2', 'rel_classes'}
      • 'classes' and 'boxes' describe the objects contained in a single image.
      • 'ix1': subject index.
      • 'ix2': object index.
      • 'rel_classes': relationship for a subject-object pair.
  • proposal.pkl

         >>> proposals.keys()
         ['confs', 'boxes', 'cls']
         >>> proposals['confs'].shape, proposals['boxes'].shape, proposals['cls'].shape
         ((1000,), (1000,), (1000,))
         >>> proposals['confs'][0].shape, proposals['boxes'][0].shape, proposals['cls'][0].shape
         ((9, 1), (9, 4), (9, 1))
         ```

Prerequisites

  • Python 2.7
  • Pytorch 0.2.0
  • opencv-python
  • tabulate
  • CUDA 8.0 or higher

Installation

  • Edit ~/lib/make.sh to set CUDA_PATH and choose your -arch option to match your GPU.

    GPU model Architecture
    TitanX (Maxwell/Pascal) sm_52
    GTX 960M sm_50
    GTX 1080 (Ti) sm_61
    Grid K520 (AWS g2.2xlarge) sm_30
    Tesla K80 (AWS p2.xlarge) sm_37
  • Build the Cython modules for the roi_pooling layer and choose the right -arch to compile the cuda code refering to https://github.com/ruotianluo/pytorch-faster-rcnn.

    cd lib
    ./make.sh

Demo

Train

  • Model Structure

Model Structure

  • Run

    cd tool
    CUDA_VISIBLE_DEVICES=0 python train.py --dataset vrd --name VRD_RANK --epochs 10 --print-freq 500 --model_type RANK_IM

 You can set the parser argument -no_so to discard separate bbox visual input and --no_obj to discard semantic cue.

  • This project contains all training and testing code for predicate detection. For relationship detection, our proposed pipeline contains two stages. The first stage is object detection and not included in this project. I am trying to release the code ASAP. Before that, you may refer to some other projects such as pytorch-faster-rcnn and faster-rcnn.pytorch.
