arcjetCV

Package to process arcjet videos and segment the edge of the shock and of the sample.

Installation

Prerequisites

The installation of the arcjetCV GUI and python package require a valid git installation, installation of the git-lfs (git large file storage) add-on and a Miniconda or Anaconda installation.

Unix Users

The software can be installed by running:

conda create --name arcjetcv conda-forge::arcjetcv

Note for macOS Users:

Please ensure that you have the Xcode Command Line Tools installed:

xcode-select --install

Windows Users and Developers

For local development of arcjetCV and for Windows users, these are the recommended installation steps:

1. Install git lfs (Git Large File Storage):

   You can download and install it from here.

2. Clone the repository and install the package:

git clone https://github.com/magnus-haw/arcjetCV.git
cd arcjetCV
conda env create -f env/arcjetCV_env_[cpu/gpu].yml
conda activate arcjetCV
python -m pip install -e . 

The -e flag stands for 'editable' and it means that any change to the local source code will have immediate effect on the arcjetCV python package and GUI.

How to Run

You can now launch the GUI by running:

conda activate arcjetCV
arcjetCV

or you can import arcjetCV's python API inside a python script, e.g. test.py:

import arcjetCV as arcv

conda activate arcjetCV
python test.py
