  • According to multiscale and accurate characterization of vehicle-license-plate (VLP) texture feature by wavelet hidden Markov tree model (WHMTM), a method of VLP Location based on WHMTM is proposed in this paper. At first high-pass filter in wavelet-domain is used as preprocessing. Afterwards VLP is segmented multiscaly from coarse to fine by WHMTM parameter of VLP. So VLP can be located from complex background fast and correctly. Experimental results show this method is very fast and robust.

Abstract: According to multiscale and accurate characterization of vehicle-license-plate (VLP) texture feature by wavelet hidden Markov tree model (WHMTM), a method of VLP Location based on WHMTM is proposed in this paper. At first high-pass filter in wavelet-domain is used as preprocessing. Afterwards VLP is segmented multiscaly from coarse to fine by WHMTM parameter of VLP. So VLP can be located from complex background fast and correctly. Experimental results show this method is very fast and robust.
