One of the most favourite languages amongst the developers, Python is well-known for its abundance of tools and libraries available for the community. The language also provides several computer vision libraries and frameworks for developers to help them automate tasks, which includes detections and visualisations.

Below here, we are listing down 10 best Python libraries that developers can use for Computer Vision.

(The list is in alphabetical order).



1| fastai

fastai is a deep learning library that provides high-level components which can quickly and easily provide state-of-the-art results in standard deep learning domains. It also provides researchers with low-level components that can be mixed and matched to build new approaches. 

fastai includes various features, such as a GPU-optimised computer vision library which can be extended in pure Python, a new type dispatch system for Python along with a semantic type hierarchy for tensors and more.

6| OpenCV

OpenCV is a popular and open-source computer vision library that is focussed on real-time applications. The library has a modular structure and includes several hundreds of computer vision algorithms. OpenCV includes a number of modules including image processing, video analysis, 2D feature framework, object detection, camera calibration, 3D reconstruction and more.

10| SimpleCV 

SimpleCV is one of the popular machine vision frameworks for building computer vision applications. Written in Python, this library helps in getting access to several high-powered computer vision libraries such as OpenCV. 

The framework is a collection of libraries and software that can be used to develop vision applications. It provides a concise, readable interface for cameras, image manipulation, feature extraction and format conversion. It also allows user to work with the images or video streams that come from webcams, Kinects, FireWire and IP cameras, or mobile phones.
