Abstract

Recently a dynamic elastic model [1] was proposed for automatic image matching. Examples were shown applying the model to dot patterns and gray scale pictures. This paper extends the model to line drawings. Examples are shown on handprint and animation, suggesting the use of dynamic matching for shape recognition and for motion correspondence.
