Why do we use cv2?

OpenCV is the huge open-source library for the computer vision, machine learning, and image processing and now it plays a major role in real-time operation which is very important in today’s systems. By using it, one can process images and videos to identify objects, faces, or even handwriting of a human.

Is Pil better than cv2?

OpenCV is written in C and C++ whereas PIL is written using Python and C, hence just from this information, OpenCV seems faster. While dealing with 1000s of images for data extraction, the processing speed 🚀 matters. Here is a quick comparison of these two libraries.
