Cascade plate recognition system

Abstract

The present invention discloses a cascade plate recognition system, wherein a compact plate region detection module receives an image, detects the plate area candidates of the image, picks out the sequences having continuous identical pixels from the plate area candidates, performs smearing and filtering on the sequences, extracts connected components from the plate area candidates to obtain compact plate regions, verifies the compact plate regions and outputs the verified compact plate regions; a plate character segmentation and recognition module receives the verified compact plate regions, extracts independent-character regions from each verified compact plate regions, verifies the independent-character regions and recognizes the verified independent-character regions to obtain the information of the plate characters. Thereby, the present invention has the advantages of high accuracy, learning capability and fast realtime operation.
