Abstract: Vehicle-logo location can be executed using edges feature of the vehicle logo depending on the position relation between vehicle-logo and vehicle license plate,then the plausibility function of vehicle-logo can be proposed by the correlation function between the original vehicle-logo and the reconstruction image reflected into the eigen vehicle-logo space from the original vehicle-logo by PCA,the error of vehicle-logo location can be reduced.After the vehicle-logo location,the vehicle-logo can be recognized by invariant moments minima moment distance depending on the stability of invariant moments features for rotation,scale,translation.The experiments result of vehicle-logo location and recognition for virtual images shows that the method is effective and practical.
