Abstract
We propose a method based on the study of wavelet transform modulus maxima to characterize signal or image edges from smoothed singularities. This characterization is used to extract robust feature points from object edges. They are tracked along an image sequence to study the motion of unrigid objects. Practical results of edge characterization and motion determination are presented
