Approach of vehicle plate extraction based on HSV color space and SIFT feature
一种基于HSV颜色空间和SIFT特征的车牌提取算法

In order to overcome the drawbacks such as slow execution speed and high mismatch rate in directly apply SIFT feature to vehicle plate extraction,this paper proposed a two steps vehicle plate extraction method based on SIFT feature and HSV color space.First roughed location the candidate region use HSV color space in a short time,then adopted SIFT feature to locate the plate precisely and correct the tilt,in the meantime accomplished the recognition task of the Chinese character on the vehicle plate.Through...
