Robotic Vision

"One of the key capabilities limiting robotic expansion at the moment is image processing -- the ability of robots to look at a scene like a human does and detect all the objects in the scene. Without general, flexible vision algorthms, it is hard for a robot to do much. For example, it is hard for a blind robot to clean a bathroom or drive a car. Part of the problem is raw CPU power, but that problem will be solved over the next 20 to 30 years because of Moore's law. The other part is a software problem. We don't have really good algorithms yet. My prediction is that we will see significant progress in the image processing field over the next 20 years.
Think about the changes that will take place once basic research in image processing yields the algorithms we need. Suddenly it will be easy for robots to walk around and manipulate objects in any human environment.

Robotic cars and trucks are one obvious application for vision systems. There are more than 40,000 deaths in the U.S. every year because of car accidents. Human negligence causes most of these accidents. With robots doing all the driving, the number of accidents will go way down and we will eliminate one of the leading causes of death in the U.S. Unfortunately, robotic vehicles will also leave every taxi driver, bus driver, truck driver, etc. out of work.
Robots with vision systems will be able to do all the cleaning in every hotel, store, airport and restaurant. Things will be spotless, but that will unemploy perhaps five million people.
Robots with vision can stack brick, lay tile, paint and put on roofs all day and all night. Five million more people will be out of work.
Robots with vision can easily stock shelves in stores. Think of all the workers stocking shelves, restocking merchandise, taking inventory, directing customers and manning cash resisters in places like Wal-Mart, K-Mart, Target, Home Depot, Lowes, BJ's, Sam's Club, Toys R Us, Sears, J.C. Penny's, Barnes and Noble, Borders, Best Buy, Circuit City, Office Max, Staples, Office Depot, Kroger's, Winn-Dixie, Pet Depot and on and on and on. More than 10 million employees will be on the street.
Armies of robots with built-in night vision will be able to provide security and policing unlike anything we can imagine today.
And so on.
A single research area -- computer vision -- will have a tremendous impact once it reaches its goal of general, flexible image processing algorithms.
This is analogous to the development of airplanes. Nothing happened in the field of aviation until the Wright Brothers made the breakthrough that got the first airplane off the ground. 44 short years after the breakthrough, supersonic flight was possible. Once robots have flexible, accurate vision systems, the pace of change will be unbelievably rapid and unstoppable."
