Paper Abstract

We develop a model-based vision approach to estimate the `aspect angle' of a target in a forward-looking infrared (FLIR) image. A set of 3-D models of military vehicles is created using a CAD/CAM package. From this set, a database of 2-D images is created by rotating the models and then projecting onto a given plane. A matching algorithm is then applied to match a signature of the given target with the images in the database. We use an algebraic approach to represent images which has the advantage that a big speedup is possible if the fast Fourier transform (FFT) is applied to compute the polynomial multiplications involved in the algebraic approach.
