Abstract. We show that we can e ectively t arbitrarily complex animation models to noisy image data. Our approach is based on leastsquares adjustment using of a set of progressively ner control triangulations and takes advantage ofthree complementary sources of information: stereo data, silhouette edges and 2 D feature points. In this way, complete head models|including ears and hair|can be acquired with a cheap and entirely passive sensor, such as an ordinary video camera. They can then be fed to existing animation software to produce synthetic sequences.
