TOBOGGAN-BASED SHAPE CHARACTERIZATION

摘要

A method (900) and apparatus (101) for characterizing an image. The method selects one or more toboggan potentials from the image, or a portion thereof, to be tobogganed (920). It toboggans the selected toboggan potentials to generate one or more toboggan parameters (930), forming at least one toboggan cluster using one or more of the toboggan parameters (940). It also selects one or more of the toboggan clusters to compute at least one feature parameter to characterize the image or a portion thereof (950).
