Applications of Splines to Shape Description

  • Theo Pavlidis

Abstract

Many image analysis problems require the description of the shape of sequences of pixels. Such pixel sequences are usually contours or skeletons obtained by processing of images. The pixels are usually but not always adjacent. Early work has emphasized polygonal approximations of the pixel sequence [1]. Such approximations provide a certain degree of data compaction and noise removal but they do not go far enough. If the shape is not polygonal to start with the representation can be unwieldy.
