About TGGLinesPlus

TGGLinesPlus is a free, open-sourced Python implementation of the TGGLinesPlus algorithm for line detection from images released by the GeoAIR Lab (https://geoair.lipingyang.org/). Many problems can be moved forward through TGGLinesPlus, including but not limited to the following: advanced optical character recognition (OCR) techniques, road lane line extraction for real-time autonomous driving, concrete cracks analysis in structural engineering, AutoCAD map vectorization, contour map digitalization, medical image processing and analysis, in addition to feature extraction for machine learning algorithms.

TGGLinesPlus paper

TGGLinesPlus algorithm is detailed in the paper, titled "TGGLinesPlus: A robust topological graph-guided computer vision algorithm for line detection from images".

Files

  • .gitignore
    Globally ignored files by git

  • environment.yml
    conda environment description of relevant dependencies

To recreate the conda environment we use in this repository, please run:

conda env create -f environment.yml

And to activate the environment:

conda activate skeleton_graph

If you should ever want to export the full list of package dependencies from this conda environment, you can run:

conda env export --no-builds | grep -v "prefix" > environment.yml
  • --no-builds: this is an attempt to make this miniconda environment work on across different operating systems by removing the build information for each package. To read more about this and how to fix any issues you run into if the above commands for installing the environment don't work for you, please see this excellent post
  • grep -v "prefix": this hides the prefix portion of the YAML file that lists the directory for where your miniconda environments are housed. This is likely to be different from one computer to the next, so it is not necessary, and hides full path information if you are working in data-sensitive environments.
