Sichere Identifikation mit Vorauswahl und Rueckweisungsklasse

Object or person classification method using image data or speech signals - applying indeterminate preselection to necessary information in several classes, and performing identification on sufficient information region to firm up indeterminate preselection with respect to actual target class.

The method involves classifying pattern, i.e. objects and dividing the information content of a pattern into two information regions. The first region contains necessary information and the second sufficient information. The necessary information region is subjected to an indeterminate preselection applied to several, but a strictly limited number of, classes. An identification is performed using the sufficient information region to firm up the indeterminate preselection with respect to an actual target class. USE - E.g. for industrial production, biometry person recognition, medical image processing. ADVANTAGE - Provides better quality of classification, e.g. by using new classifiers or new classification sets.
