Shape Description With An Associative Memory

In this paper a new shape classification scheme is proposed which uses the image processing formalism of associative memory mappings. This scalar transform technique is applied to two-dimensional (2D) images. The shape description is the centroidal profile which is the radius as a function of arc length parametrization of the boundary. Other one-dimensional (1D) representations are also discussed. The scheme is applicable to both full- and partial-view recognition problems. The restoration of degraded images, either due to occlusion or other forms of information loss, is optimal in the least squares sense.
