1. A method comprising: detecting one or more interest points within at least one image of a vehicle; determining one or more descriptors that correspond to at least one of the one or more interest points; based on a failure of a license plate recognition process, selecting one or more templates, each of the one or more templates comprising one or more descriptors determined in relation to one or more previously obtained images; matching, by a processor, at least one of the one or more of the descriptors that correspond to the at least one of the one or more interest points to the one or more templates; calculating a confidence measure of a match between (a) the at least one of the one or more of the descriptors that correspond to the at least one of the one or more interest points and (b) at least one of the one or more of the templates; and identifying one or more identity parameters of the vehicle based on the confidence measure.
