How To Install python3-opencv on Kali Linux
Introduction
In this tutorial we learn how to install python3-opencv on Kali Linux.
What is python3-opencv
python3-opencv is:
This package contains Python 3 bindings for the OpenCV (Open Computer Vision) library.
The Open Computer Vision Library is a collection of algorithms and sample code for various computer vision problems. The library is compatible with IPL (Intel’s Image Processing Library) and, if available, can use IPP (Intel’s Integrated Performance Primitives) for better performance.
OpenCV provides low level portable data types and operators, and a set of high level functionalities for video acquisition, image processing and analysis, structural analysis, motion analysis and object tracking, object recognition, camera calibration and 3D reconstruction.
There are three methods to install python3-opencv on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install python3-opencv Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get updateAfter updating apt database, We can install python3-opencv using apt-get by running the following command:
sudo apt-get -y install python3-opencvInstall python3-opencv Using apt
Update apt database with apt using the following command.
sudo apt updateAfter updating apt database, We can install python3-opencv using apt by running the following command:
sudo apt -y install python3-opencvInstall python3-opencv Using aptitude
If you want to follow this method, you might need to install aptitude on Kali Linux first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude using the following command.
sudo aptitude updateAfter updating apt database, We can install python3-opencv using aptitude by running the following command:
sudo aptitude -y install python3-opencvHow To Uninstall python3-opencv on Kali Linux
To uninstall only the python3-opencv package we can use the following command:
sudo apt-get remove python3-opencvUninstall python3-opencv And Its Dependencies
To uninstall python3-opencv and its dependencies that are no longer needed by Kali Linux, we can use the command below:
sudo apt-get -y autoremove python3-opencvRemove python3-opencv Configurations and Data
To remove python3-opencv configuration and data from Kali Linux we can use the following command:
sudo apt-get -y purge python3-opencvRemove python3-opencv configuration, data, and all of its dependencies
We can use the following command to remove python3-opencv configurations, data and all of its dependencies, we can use the following command:
sudo apt-get -y autoremove --purge python3-opencvDependencies
