ABSTRACT:
Two data sets are analyzed to determine disparity between them at various interrogation regions (302) of the data sets. The data sets can represent, for example, digital images, acoustical signals, or electrical signals. The size of interrogation regions (302) used for disparity analysis is varied dynamically. An initial interrogation region (302) from a reference data set is compared to several candidate regions (304) from a target data set. If none of the comparisons indicate a required level of similarity, the process is repeated with a larger interrogation region (302). This process of successively using larger interrogation regions (302) continues until either a maximum interrogation region (302) size is reached, or the required level of similarity is indicated in one of the comparisons.
