[2020/12/07] Testing dataset will be update after the release of official link by workshop organizer.
In this paper, we present a novel deep neural network, termed Parallel Reverse Attention Network (PraNet), for the task of automatic polyp segmentation at MediaEval 2020. We give the brif description here:
Technical Details. Specifically, we first aggregate the features in high-level layers using a parallel partial decoder (PPD). Based on the combined feature, we then generate a global map as the initial guidance area for the following components. In addition, we mine the boundary cues using the reverse attention (RA) module, which is able to establish the relationship between areas and boundary cues.
High Performance and Efficiency. Thanks to the recurrent cooperation mechanism between areas and boundaries, our PraNet is capable of calibrating misaligned predictions, improving the segmentation accuracy and achieving real-time efficiency (30fps) on a single NVIDIA GeForce GTX 1080 GPU.
Training Strategy. We introduce four data augmentation strategies into the dataloader, such as random horizontal flipping, rotating, color enhancement and border cropping. These strategies is able to enhance the capability and generalizability of the model in the practial scene.

I recommend that you enter the commands step-by-step in the terminal, due to different machine may encounter some problems.
#!/usr/bin/env bash
# confirm your server have install `anaconda`
# (NOTE: in this phase, you need confirm the installation via enter `Y` manually)
conda create -n pranet python=3.6
# activate your virtual environment
# (NOTE: if this step is invalid, you must activate it manually)
conda activate pranet
# install necessary packages for PyTorch
# (NOTE: in this phase, you need confirm the installation via enter `Y` manually)
conda install pytorch=1.3.1 torchvision=0.4.2 cudatoolkit=10.0
# install necessary packages for necessary libs
pip install opencv-python==3.4.2.17 tensorboardX==2.0-
We randomly select train/validation (90% / 10%) samples from Kavasir-SEG dataset. You can download it from this link (upcoming soon~) and put it in
./data/. -
run
python Training.py
-
Following the protocol defined in the workshop instructions, we prepare the test set. (Note that we do not have ground-truth until now, and we will update it later)
-
Download the model weights from google drive
-
Put it into
./snapshot/Net_epoch_best.pth -
Run
python Testing.py
