    Abstract

    A location method combining of the fusion for color and edge features with the object authenticity confirmation is presented to solve the problem of Vehicle License Plate (VLP) location under complex environments.The algorithm fused by color features and edge features can extract all possible objects because the vehicle license plate is charaterized by its fixed color assortments and rich charater edges.Then,the object authenticity confirmation by virtue of the features of concomitance and complement is used to realize a feedback location to obtain the multi-object or multi-type object locations under complex environments.An experiment is undertaken with 981 actual RGB color images from various complex environments,and the experimental results show that the object location accuracy is over 99 percent,which proves the proposed object location method is effective and practical.
