A Method for Segmenting the Self-Lighting Type License Numbers of Cars Using Image Processing Techniques

This letter presents a technique to segment the character number region from the self-lighting in the night. From the histograms of R, G and B images, the image of the parts of lights are eliminated and another image derived from the Gauss-Laplacian operation and binarization operation of the G image are processed by Logic operation of AND, then characters are extracted. Our examinations conclude that it is a effective way to segment the character region on number and satisfactory results are obtained.
