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.
