　　A cookbook of algorithms for common image processing

applicati***

Thanks to advances in computer hardware and software,

algorithms have been developed that *** sophisticated image

processing without requiring an extensive background in

mathematics. This bestselling book has been fully updated with the

newest of these, including 2D vision methods in content-based

searches and the use of graphics cards as image processing

computational aids. It’s an ideal reference for software engineers

and developers, advanced programmers, graphics programmers,

scientists, and other specialists who require highly specialized

image processing.

Algorithms now exist for a wide variety of sophisticated image

processing applicati*** required by software engineers and

developers, advanced programmers, graphics programmers, scientists,

and related specialists

This bestselling book has been completely updated to include the

latest algorithms, including 2D vision methods in content-based

searches, details on modern classifier methods, and graphics cards

used as image processing computational aids

Saves hours of mathematical calculating by using distributed

processing and GPU programming, and gives non-mathematicians the

shortcuts needed to program relatively sophisticated

applicati***.

Algorithms for Image Processing and Computer Vision, 2nd Edition

provides the tools to speed development of image processing

applicati***.
