a field that includes methods for acquiring, processing, analyzing, and understanding images and, in general, high-‐ dimensional data from the real world in order to produce numerical or symbolic informa4on, e.g., in the forms of decisions. A theme in the development of this field has been to duplicate the abili4es of human vision by electronically perceiving and understanding an image. This image understanding can be seen as the disentangling of symbolic informa4on from image data using models constructed with the aid of geometry, physics, sta4s4cs, and learning theory. Computer vision has also been described as the enterprise of automa4ng and integra4ng a wide range of processes and representa4ons for vision percep4on.” (Wikipedia 2014 h^p://en.wikipedia.org/wiki/Computer_Vision)
computer vision applica4ons. With it, you get access to several high-‐powered computer vision libraries such as OpenCV – without having to first learn about bit depths, file formats, color spaces, buffer management, eigenvalues, or matrix versus bitmap storage. h^p://simplecv.org/ Demo: SimpleCV -‐ The Basics.ipynb Pygame dependency caused me some problems Not all image manipula4on worked in ipython.
