00005 
00006   The <b>pcl_keypoints</b> library contains implementations of two point cloud keypoint detection algorithms.
00007   Keypoints (also referred to as <a href="http://en.wikipedia.org/wiki/Interest_point_detection">interest points</a>) 
00008   are points in an image or point cloud that are stable, distinctive, and can be identified using a well-defined 
00009   detection criteron.  Typically, the number of interest points in a point cloud will be much smaller than the total
00010   number of points in the cloud, and when used in combination with local feature descriptors at each keypoint, the 
00011   keypoints and descriptors can be used to form a compact&mdash;yet descriptive&mdash;representation of the original 
00012   data.
