7 Best Image Processing Libraries in Python: A Comprehensive Guide for Developers

Data has become increasingly valuable in today’s digital landscape, with images making up a significant portion. Data scientists process these images and feed them into machine learning (ML) models to gain deep insights for businesses.

Image processing involves converting images into digital forms and performing operations on them to extract valuable information. Common types of image processing include visualization, recognition, sharpening and restoration, pattern recognition, and retrieval.

Python provides an extensive range of image processing libraries for various applications, such as medical research, recovering and reconstructing corrupted images, and face detection. Key image processing libraries in Python include:

1. OpenCV: An open-source library developed by Intel. It is popular for numerous computer vision tasks like face detection, object detection, and image segmentation.

2. Scikit-Image: A versatile library used for almost every computer vision task. It offers various algorithms for segmentation, color space manipulation, geometric transformation, and more.

3. SciPy: Originally designed for mathematical and scientific computations, it is now a top library for multidimensional image processing through the scipy.ndimage submodule.

4. Mahotas: Initially designed for bioimage informatics, Mahotas offers advanced features like local binary patterns and haralick texture features. It can compute 2D and 3D images.

5. Pillow (PIL): An open-source library evolved from the Python Imaging Library. It is capable of handling various image formats while providing image processing methods.

6. SimpleITK: A library that considers images as a set of points on a physical region in space, supporting 2D, 3D, and 4D dimensions. It is primarily used for image segmentation and registration.

7. Matplotlib: An image module designed for 2D plots of arrays and reading/displaying images. It is often used for 2D visualizations, while also extracting information from images.

These libraries are widely used for tasks like feature extraction, segmentation, filtering, and image manipulation. Integrating them into your work will greatly enhance your ability to process images and develop insights for your business.
