Line 9:

Typically, patterns are constructed from simpler sub patterns in a hierarchical fashion. This helps in dividing the recognition task into easier subtask of first identifying sub patterns and only then the actual patterns.

Structural methods provide descriptiondescriptions of items, which may be useful onin itstheir own right. For example, syntactic pattern recognition can be used to find out what objectobjects are present in an image. Furthermore, structural methods are strong in finding a '''correspondence mapping''' between two images of an object. Under natural conditions, corresponding features will be in different positions and/or may be occluded in the two images, due to camera-attitude and perspective, as in [[face recognition]]. A graph-matching algorithm will yield the optimal correspondence.
