Making The Computer See: Computer Vision For Everyday Applications With a camera and a powerful computer in every pocket, the shift from typing to computer vision is just about to happen. Instead of entering information about a wine for our tasting notes, we snap a photo and let the computer recognize it and look up the information. Instead of having the shopper enter his credit card info, we can read the information straight from the card with the camera. We can even use computer vision to play a fanfare when someone arrives at our doorstep carrying a pizza box. The tools to make this happen are in the field of computer vision. Today, the are solid techniques and cross-platform open-source libraries such as OpenCV available that make it easy to build this into everyday applications.
