Recently, a new technique for the lossless encoding of contour maps was introduced, based on the concept of "transition points". In this paper, we show that by using a simple representation for the transition points, i.e., the map of transition points, the problem of encoding arbitrary contour maps can be easily converted into a problem of lossless image coding. Experimental results show that the Joint Bilevel Image Experts Group (JBIG) image coding standard can be used successfully for encoding maps of transition points, outperforming, in most cases, differential chain-coding. Moreover, if we take into account that JBIG codecs are available as "off-the-shelf" components, then the effort required to implement the proposed method is small.
最近，一种基于“过渡点”概念的轮廓图无损编码新技术被提出。本文表明，通过使用过渡点的简单表示，即过渡点图，可以将任意轮廓图的编码问题轻松转换为无损图像编码问题。实验结果表明，联合双层图像专家组 (JBIG) 图像编码标准可成功用于编码过渡点图，在大多数情况下，其性能优于差分链式编码。此外，如果我们考虑到 JBIG 编解码器可作为“现成”组件使用，那么实现所提出方法所需的工作量很小。
