Introduction
|
||
|
|
------------
|
||
|
|
ANN is a library written in the C++ programming language to support both
|
||
|
|
exact and approximate nearest neighbor searching in spaces of various
|
||
|
|
dimensions. It was implemented by David M. Mount of the University of
|
||
|
|
Maryland, and Sunil Arya of the Hong Kong University of Science and
|
||
|
|
Technology. ANN (pronounced like the name ``Ann'') stands for
|
||
|
|
Approximate Nearest Neighbors. ANN is also a testbed containing
|
||
|
|
programs and procedures for generating data sets, collecting and
|
||
|
|
analyzing statistics on the performance of nearest neighbor algorithms
|
||
|
|
and data structures, and visualizing the geometric structure of these
|
||
|
|
data structures.
|
||
|
|
|
||
|
|
The ANN source code and documentation is available from the following
|
||
|
|
web page:

For more information on ANN and its use, see the ``ANN Programming
|
||
|
|
Manual,'' which is provided with the software distribution.
