How To Install opencv on Fedora 34
opencv is Collection of algorithms for computer vision Collection of algorithms for computer vision
Introduction
In this tutorial we learn how to install opencv on Fedora 34.
What is opencv
OpenCV means Intel® Open Source Computer Vision Library. It is a collection of C functions and a few C++ classes that implement some popular Image Processing and Computer Vision algorithms. opencv 4.5.2 2.fc34 x86_64 1.4 M opencv-4.5.2-2.fc34.src.rpm updates Collection of algorithms for computer vision https BSD OpenCV means Intel® Open Source Computer Vision Library. It is a collection of C functions and a few C++ classes that implement some popular Image Processing and Computer Vision algorithms.
We can use yum or dnf to install opencv on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install opencv.
Install opencv on Fedora 34 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
Fedora 34 - x86_64 20 kB/s | 6.6 kB 00:00
Fedora 34 openh264 (From Cisco) - x86_64 1.4 kB/s | 989 B 00:00
Fedora Modular 34 - x86_64 68 kB/s | 6.5 kB 00:00
Fedora 34 - x86_64 - Updates 3.5 kB/s | 6.2 kB 00:01
Fedora Modular 34 - x86_64 - Updates 17 kB/s | 5.9 kB 00:00
Metadata cache created.
After updating yum database, We can install opencv using dnf by running the following command:
sudo dnf -y install opencv
Install opencv on Fedora 34 Using yum
Update yum database with yum using the following command.
sudo yum makecache --refresh
The output should look something like this:
Fedora 34 - x86_64 20 kB/s | 6.6 kB 00:00
Fedora 34 openh264 (From Cisco) - x86_64 1.4 kB/s | 989 B 00:00
Fedora Modular 34 - x86_64 68 kB/s | 6.5 kB 00:00
Fedora 34 - x86_64 - Updates 3.5 kB/s | 6.2 kB 00:01
Fedora Modular 34 - x86_64 - Updates 17 kB/s | 5.9 kB 00:00
Metadata cache created.
After updating yum database, We can install opencv using yum by running the following command:
sudo yum -y install opencv
How To Uninstall opencv on Fedora 34
To uninstall only the opencv package we can use the following command:
sudo dnf remove opencv
