What makes a nose a nose?

In the field of computer vision, scientists frequently find themselves asking such questions.  Creating an algorithm to help computers identify shapes has turned out to be a task ridden with problems.  

With traditional shape-identification methods, an algorithm would have to cover thousands of nose-shape variations, not to mention exhaustive definitions for the numerous other objects a computer may have to identify.  A human can identify a nose as a nose regardless of deformities, lighting conditions, etc., but it's proven infinitely more difficult for a computer to achieve this same flexibility.  

However, a new computer-vision technique has taken a huge step to overcoming this barrier.  Read the full article about the closest we've come to giving computers sight.

The most common question students ask math teachers at every level is “When will I use math?” is a non-profit website that helps to answer this question. This website describes the importance of mathematics and many rewarding career opportunities available to students who study mathematics.
