Approximate Nearest Neighbors Search in Multi-Dimensional Spaces

Detailed Description

This section documents OpenCV's interface to the Annoy. Annoy (Approximate Nearest Neighbors Oh Yeah) is a library to search for points in space that are close to a given query point. It also creates large read-only file-based data structures that are mmapped into memory so that many processes may share the same data.
