PolygonRNN++

This is the official inference code for Polygon-RNN++ (CVPR-2018). For technical details, please refer to:

An official pytorch reimplementation with training/tool code is available here

Efficient Interactive Annotation of Segmentation Datasets with Polygon-RNN++
David Acuna*, Huan Ling*, Amlan Kar*, Sanja Fidler (* denotes equal contribution)
CVPR 2018
[Paper] [Video] [Project Page] [Demo] [Training/Tool Code] Model

Usage

  1. Clone the repository
git clone https://github.com/davidjesusacu/polyrnn && cd polyrnn
  1. Install dependencies
    (Note: Using a GPU (and tensorflow-gpu) is recommended. The model will run on a CPU, albeit slowly.)
virtualenv env
source env/bin/activate
pip install -r requirements.txt
  1. Download the pre-trained models and graphs (448 MB)
    (These models were trained on the Cityscapes Dataset)
./models/download_and_unpack.sh 
  1. Run demo_inference.sh
./src/demo_inference.sh 

This should produce results in the output/ folder that look like ex2 ex1

Walkthrough

Checkout the ipython notebook that provides a simple walkthrough demonstrating how to run our model on sample input image crops
