A scheme for extracting morphological information from images through a edge oriented wavelet decomposition is proposed. Multiresolution edge patterns extracted in the wavelet transform domain are represented by parameterized segments. Tracking these segments across consecutive frames of a sequence leads to a parametric cinematic characterization of the content of a video sequence, suited for high level syntactic processing. Parameterized images are visualizable by means of the inverse wavelet transform.
