Generally,　the　traditional　algorithms　of　vehicle　license　plate　location　are　not　able　to　deal　with　different　kinds　of　license　plates.　In　order　to　solve　this　problem,　after　considering　the　characteristics　of　color,　edge,　texture　and　geometry　size　around　license　plate,　a　morphology　method　based　on　modified　top-hat　transform　is　presented　in　this　paper.　The　experimental　result　shows　that　this　new　method　has　strong　robustness　and　can　be　applied　in　various　conditions.
