OpenCV vs PIL/Pillow: which is better for image processing tasks?
OpenCV is well-suited to advanced, performance-focused image processing and computer vision applications, efficiently handling tasks such as filtering, transformation, object detection, and edge extraction. Pillow (the Python Imaging Library successor) is best for simple image processing - such as cropping, resizing, and file conversion - and integrates easily into basic Python workflows. For large, complex, or high-speed photo analysis pipelines, OpenCV offers more power and flexibility than PIL/Pillow.
