Pattern recognition is defined as the automatic identification of figures, characters, shapes, forms and patterns without active human participation in the decision process. These can be structures in one dimension, for example an array of characters, a time series or any other signal, or a structure in two dimensions, such as an image. Higher dimensional patterns are rarely if ever encountered. Pattern recognition can be further divided into recognizing existing features that have a well-known effect on an image, or the search for coherent subpatterns that may have a common cause. A pattern therefore consists either of features that are known to exist, but are somehow difficult to identify, or of features that may get a specific meaning afterwards (i.e. after they are detected).
