An efficient and fast method for vehicle license plate detection in complex background is proposed in this paper. It uses several convolution pattern filters to enhance character strokes while reducing irrelevant edges and background noise. Experimental results show that our proposed method has very high detection accuracy and low false positive rate compared with former methods based on edge detection...
For the limitation of current license plate location algorithms, present an algorithm of the license plate location based on image energy and its practical formulas. Introduce the algorithm of extraction and methods to verify region of license plate. It takes full advantage of characteristics of the license plate, such as complicated textures, sharp-cut contrast and so on. It also has the advantages...
