Abstract
Because of low precision of license plate location in the color vehicle images with complex background, a new License Plate Location Algorithm was proposed based on multi-scale edge detection method with wavelet transform. Firstly, we perform WT on two directions respectively, and obtain the magnitude of the 2-D WT. Then detect the maxima magnitude of WT as the image edge and get edge image. At last, the projection approach based on two-way back is adopted to examine up-down and left-right boundary of the car license. Experimental results demonstrate that the proposed method can enhance the images location speed and accurate capture license plate region.
