| Abstract: | The paper introuduces a license plate location algorithm with an adaptive threshold based on an improved texture characteristics for precise location.The feature of character segmentation lies in the projection threshold which is able to change according to different images.Finally BP neural network is used to identify each character.Experimental results show that the method can achieve accurate license plate recognition. |
