Abstract: A novel search strategy for local region based on hierarchical region detection is proposed. All local regions of interest satisfying candidate detection condition are extracted using this strategy. Then the fine plate location, including gradient enhancement, redundant edge removing and plate segmentation, is performed sequentially. Experiments results show that the proposed method possesses strong robustness to environmental noise and provides high accuracy of real-time license plate location.

Key words: computer application, license plate location, hierarchical strategy, gradient enhancement, region of interest
