Main results

Performance on Kvasir-SEG Dataset

(Training/Testing split = 880/120 according to Real-Time Polyp Detection, Localisation and Segmentation in Colonoscopy Using Deep Learning) (FPS measures on 2080Ti)

Performance on Kvasir-SEG Dataset

(Training/Testing split = 1450 from 5 datasets /100 from Kvasir-SEG according to PraNet: Parallel Reverse Attention Network for Polyp Segmentation) (FPS measures on 2080Ti)

Sample Inference Results of Kvasir-SEG Dataset comparing with PraNet

HarDNet-MSEG Architecture

• A Simple Encoder-Decoder architecture

• Encoder Part : Using HarDNet68 as backbone

    + k = growth rate (as in DenseNet)
    + m = channel weighting factor (1.6~1.7)
    + Conv3x3 for all layers (no bottleneck layer)
    + No global dense connection (input of a HarDBlk is NOT reused as a part of output)

• Decoder Part : Adopted from Cascaded Partial Decoder

    + Using RFB Block for increasing the receptive field and strengthening the features.
    + Dense aggregation for fusing the features.

Installation & Usage

1. Training/Testing

• Environment setting (Prerequisites):

  • conda create -n *your_env_name* python=3.6.

  • Then install PyTorch 1.1.

• Downloading necessary data:

  For Kvasir-SEG Dataset reference from Real-Time Polyp Detection, Localisation and Segmentation in Colonoscopy Using Deep Learning (Only training using Kvasir-SEG, 880 images for training 120 images for testing)

  • downloading testing dataset and move it into your test_path which can be found in this download link (Google Drive).

  • downloading training dataset and move it into your train_path which can be found in this download link (Google Drive).

  For each Dataset training including Kvasir-SEG, CVC-ColonDB, EndoScene, ETIS-Larib Polyp DB and CVC-Clinic DB from PraNet: Parallel Reverse Attention Network for Polyp Segmentation

  • downloading testing dataset and move it into your test_path which can be found in this download link (Google Drive).

  • downloading training dataset and move it into your train_path which can be found in this download link (Google Drive).

• Training :

  1. First download pretrain_weight : hardnet68.pth for HarDNet68 in https://github.com/PingoLH/Pytorch-HarDNet

  2. Change the weight path in lib/hardnet_68.py line 203 for loading the pretrain_weight

  3. Change the --train_path & --test_path in Train.py

  4. Final step is to run the Train.py

• Testing & inference result :

  1. Change the data_path in Test.py (line 16)

  2. Here is the weight we trained for Kvasir-SEG using on the report https://drive.google.com/file/d/1nj-zv64RiWwYjCmWg4NME7HNf_nBncUu/view?usp=sharing

     Download it, and run "python Test.py --pth_path "path of the weight"

     And you can get the inference results in results/

Evaluation :

1. Change the image_root, gt_root in line 49, 50 in eval_Kvasir.py
2. Run the eval_Kvasir.py to get a similar result (about +0.002) to our report for Kvasir Dataset.

Another one is written in MATLAB code (link). You can see how to run it in https://github.com/DengPingFan/PraNet#32-evaluating-your-trained-model- And our report is using this code to evaluate.
