摘要：

A multiple point smoothing algorithm is proposed to smooth a binary image boundary further based on a previously proposed one point smoothing algorithm. A new feature extraction method is also presented. The smoothing and feature extraction algorithms are all based on the chain codes. The effectiveness of these algorithms is demonstrated with binary images of handwritten numerals. (C) 1998 Elsevier Science B.V. All rights reserved.
