Description

This is a PyTorch Implementation of DCLNet " Disentangled Contour Learning for Quadrilateral Text Detection ".

ICDAR2017 MLT	Precision	Recall	F-score
DCLNet	81.0	66.9	73.3
DCLNet*	81.9	71.4	76.3

Prerequisites

Only tested on

• Anaconda3
• python 3.7.1
• torch 1.2.0
• torchvision 0.4.0
• opencv-python 4.4.0.42
• easydict 1.9

Installation

1. LANMS

Refer to LANMS

2. DCN

Refer to DCN in DBNet. Note that this repo puts dcn in the model dir.

3. Clone

git clone https://github.com/SakuraRiven/DCLNet.git
cd DCLNet

4. Data & Pre-Trained Model

• ICDAR2017, SynthText

• backbone

• pretrained model

• finetune model

Make a new folder pths and put the download pths into pths

mkdir pths
cd pths
mkdir backbone pretrain train
cd ..
mv resnet50-19c8e357.pth pths/backbone/
mv model_epoch_5.pth pths/pretrain/
mv model_epoch_150.pth pths/train/
