ELSED: Enhanced Line SEgment Drawing

This repository contains the source code of ELSED: Enhanced Line SEgment Drawing the fastest line segment detector in the literature. It is ideal for resource-limited devices like drones of smartphones. Visit the Project Webpage to try it online!

Dependencies

The code depends on OpenCV (tested with version 4.1.1).

# Install dependencies (Ubuntu 18.04)
sudo apt-get install -y build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
# Download source code
git clone https://github.com/opencv/opencv.git --branch 4.1.1 --depth 1
# Create build directory
cd opencv && mkdir build && cd build
# Generate makefiles, compile and install
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make -j
sudo make install

Compile and Run

The code contains a demo detecting large and short line segments in one image. The code can be compiled with Cmake:

mkdir build && cd build
cmake .. && make
./elsed_main

The result for the provided image should be:

******************************************************
******************* ELSED main demo ******************
******************************************************
ELSED detected: 305 (large) segments
ELSED detected: 391 (short) segments
