Abstract: An object localization system including an object detection module configured to detect an object in a current frame with reference to a preceded frame, and an object localization module configured to identify a location of the object according to the segment. The object detection module includes a difference module for computing differences between the preceded frame and the current frame at a same location to generate a difference frame, a selected block detection module for identifying a selected block of the difference frame according to a predetermined minimum difference, a segment generation module for generating a segment of the current frame.

Abstract: A license plate recognition system includes an image capturing module, a license plate detection module, a segment extraction module, a character classification module, and a character recognition module. The image capturing module is for capturing an image. The license plate detection module is for receiving the image and to identify a license plate in the image. The segment extraction module is for extracting a sequence of character segments on the license plate. The character classification module is for computing a probability of each possible character in each character segment. The character recognition module is for identifying permissible characters for the each character segment according to a syntax of the sequence of character segments, and to identify a character having a highest probability among the permissible characters as a selected character for the each character segment.
