Title
Shape Recognition Algorithm Robust under Partial Occlusions and Affine Deformations
Abstract
We design a generic contrast and affine invariant planar shape recognition algorithm. By generic, we mean an algorithm which delivers a list of all shapes two digital images have in common, up to any affine transform or contrast change. Affine invariance must not be considered as a weak requirement in shape recognition since it is well known that if 3D objects with smooth boundaries are being observed, then the deformation of the objects’ images, far enough from the occlusion boundaries, is locally an affine transform. We define as ”shape elements” all pieces of level lines of the image. We then discuss an efficient local encoding of the shape elements. We finally show experiments. Applications aimed at include image registration, image indexing, optical flow.
