SimpleCV is described as 'Python interface to several powerful open source computer vision libraries in a single convenient package. With it, your software can have access to high level algorithms in feature detection, filtering, and pattern recognition in a unified framework' and is an app in the development category. There are three alternatives to SimpleCV for Mac, Windows, Linux, Android and Chrome OS. The best SimpleCV alternative is OpenCV, which is both free and Open Source. Other great apps like SimpleCV are BoofCV and Landing AI Python SDK.
