Shape recognition using machine learning

Computer vision is a growing field of computer science that intends to extract some useful information from images, usually taken from cameras or scanners. The ability to recognize shapes in images is often necessary in computer vision programs. This article describes how to make a program able to recognize basic geometrical figures by using machine learning. This article shows the image processing stages until feature extraction; Giving to the reader an idea of how to apply computer vision for other problems that involve shape recognition.
