Perspective Field Network

Code Repo of 'Rethinking Planar Homography Estimation Using Perspective Fields'

Tensorflow/Keras implementation for reproducing Perspective Network (PFNet) results in the paper Rethinking Planar Homography Estimation Using Perspective Fields by Rui Zeng, Simon Denman, Sridha Sridharan, Clinton Fookes.

COCO Dataset

• Please refer to Common Objects in Context to download the dataset used in the paper.

Trained Weights.

• Download our trained weights from provisionally trained weights and put it in the root directory

Dependencies

python 3.6

• Tensorflow >= 1.5.0
• Keras >= 2.2.0
• Opencv >= 3.0.0

In addition, please add the project folder to PYTHONPATH and pip install the packages if ImportError: No module named xxx error message occur.

Training

• Train a PFNet model on the COCO dataset from scratch:
  • python train.py --dataset=/home/COCO

Evaluation

• Evaluate the *.h5 model checkpoint
  • python evaluate.py --dataset=/home/COCO --model=./pfnet.h5
