Abstract :
We present a new approach for recognizing the make and model of a car from a single image. While most previous methods are restricted to fixed or limited viewpoints, our system is able to verify a car´s make and model from an arbitrary view. Our model consists of 3D space curves obtained by backprojecting image curves onto silhouette-based visual hulls and then refining them using three-view curve matching. We also build an appearance model of taillights which is used as an additional cue. Our approach is able to verify the exact make and model of a car over a wide range of viewpoints and background clutter.
