Introduction

Vision-Language Transformer (VLT) is a framework for referring segmentation task. Our method produces multiple query vector for one input language expression, and use each of them to “query” the input image, generating a set of responses. Then the network selectively aggregates these responses, in which queries that provide better comprehensions are spotlighted.

Installation

  1. Environment:

    • Python 3.6

    • tensorflow 1.15

    • Other dependencies in requirements.txt

    • SpaCy model for embedding:

      python -m spacy download en_vectors_web_lg

  2. Dataset preparation

    • Put the folder of COCO training set ("train2014") under data/images/.

    • Download the RefCOCO dataset from here and extract them to data/. Then run the script for data preparation under data/:

      cd data
      python data_process_v2.py --data_root . --output_dir data_v2 --dataset [refcoco/refcoco+/refcocog] --split [unc/umd/google] --generate_mask
      

Evaluating

  1. Download pretrained models & config files from here.

  2. In the config file, set:

    • evaluate_model: path to the pretrained weights
    • evaluate_set: path to the dataset for evaluation.
  3. Run

    python vlt.py test [PATH_TO_CONFIG_FILE]
    

Training

  1. Pretrained Backbones: We use the backbone weights proviede by MCN.

    Note: we use the backbone that excludes all images that appears in the val/test splits of RefCOCO, RefCOCO+ and RefCOCOg.

  2. Specify hyperparameters, dataset path and pretrained weight path in the configuration file. Please refer to the examples under /config, or config file of our pretrained models.

  3. Run

    python vlt.py train [PATH_TO_CONFIG_FILE]
    

Acknowledgement

We borrowed a lot of codes from MCN, keras-transformer, RefCOCO API and keras-yolo3. Thanks for their excellent works!
