Configure Linux system to support image processing and computer vision development

In today's digital age, image processing and computer vision play an important role in various fields. In order to do image processing and computer vision development, we need to make some configurations on our Linux system. This article will show you how to configure your Linux system to support these applications and provide some code examples.

1. Install Python and the corresponding libraries

Python is a widely used programming language suitable for image processing and computer vision development. In Linux systems, we can install Python through the package manager.

First, open a terminal and enter the following command to install Python:

sudo apt-get update
sudo apt-get install python3

After the installation is complete, we can check whether the installation was successful:

python3 --version

Next, we need to install some Important Python libraries such as NumPy, OpenCV and Pillow. Execute the following command to install:

pip install numpy opencv-python pillow

After the installation is complete, we can execute some simple code to test whether the library is working properly. For example, execute the following code to read and display an image:

import cv2

image_path = 'path/to/your/image.jpg'
image = cv2.imread(image_path)

cv2.imshow('Image', image)
cv2.waitKey(0)
cv2.destroyAllWindows()

2. Install CUDA and cuDNN

If you want to use GPU for image processing and computer vision development, then we also CUDA and cuDNN need to be installed.

CUDA is a platform and API developed by NVIDIA for parallel computing. In Linux, we can download CUDA from NVIDIA's official website and install it.

After the installation is complete, we also need to install cuDNN. cuDNN is an acceleration library for deep neural networks that speeds up model training and inference.

We can download cuDNN from NVIDIA’s official website and install it.

After installing CUDA and cuDNN, we can use the following code to test whether the GPU is working properly:

import torch

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
print(device)

If the output result is "cuda", it means that the GPU has been successfully configured and available.

3. Install other image processing and computer vision tools

In addition to Python and related libraries, we can also install some other image processing and computer vision tools to assist development.

For example, ImageMagick is a powerful open source toolset that can be used to process and transform images. We can use the following command to install ImageMagick:

sudo apt-get install imagemagick

After the installation is complete, we can use the following command to test whether ImageMagick is working properly:

convert input.jpg -resize 50% output.jpg

This command will read the name "input.jpg "picture, resize it to 50% of the original size, and then save the processed picture as "output.jpg".

Through this article, we learned how to configure a Linux system to support image processing and computer vision development, and provided some code examples for reference. I hope this information is helpful to you, and I wish you good luck on your path to image processing and computer vision!
