Abstract
Lines in images, after digitization, binary conversion, and thinning, can be represented as piece-wise linear curves on a two-dimensional plane. The piece-wise linear plane curves may be converted to regularized curvature functions by the use of kernel functions. The method of kernel functions gives position, orientation, and if desired, length invariant representations of the piece-wise linear curves, and produces controllably smooth descrip-tions while preserving the overall shape of the original curve. The method is applicable to shape description for matching, identification and smooth reconstruction.© (1984) COPYRIGHT SPIE--The International Society for Optical Engineering.
