August 13, 2012  Computer vision systems can now recognize
thousands of objects  The field of computer vision has vastly
improved since it began in the 1960s. Computers can now quickly
and accurately recognize thousands of faces, as well as a
growing number of other objects. Although computer vision
currently lacks the subtlety, versatility, and general
capabilities of human vision, the gap is steadily closing. Dr.
Fei Fei Li is an expert on the field of computer vision, and she
and her colleagues at Stanford University are working on
advancing the state of the art. In an interview with Sander
Olson for Next Big Future, Dr. Li describes the importance of
math and algorithms to computer vision, and why she believes
that computer vision systems may be able to match human visual
systems within the next twenty years.  Fei-Fei Li  Question: You
have been working in the field of computer vision for more than
a decade. How has the field changed since you started?  The
field of computer vision has grown in all dimens
