Class Information
Number: 382/201
Name: Image analysis > Pattern recognition > Feature extraction > Local or regional features > Point features (e.g., spatial coordinate descriptors)
Description: Subject matter including any of the following: an image is sampled at only a few key locations to determine whether essential points in a pattern* are present at those locations; every measurement on the image results in a set of values representing spatial coordinates only; or each of the features sought within a pattern* can be defined by a specific point.
