提出了一种多尺度曲线和边界编码器。它利用了多尺度结构-细光束-主要是为线性和曲线特征设计的。编码器由三个主要组件组成：1）基于率失真优化的小波束表示，2）从小波束表示到符号流的基于树的编码，以及3）熵编码器。这个编码器被命名为“JBEAM”。利用其多尺度特性，我们利用基于树的编码，使其渐进。推导出的编码器具有较低的计算复杂度。仿真结果表明，它优于最先进的工业标准：JBIG 2。提供了一个软件包，其中包括JBEAM的执行。将讨论这种方法的变化和潜在的改进。这项工作可能会激发更多的活动，在这条线的研究，改善曲线编码。
A multiscale coder for curves and boundaries is presented. It utilizes a multiscale structure-beamlets-that is designed primarily for linear and curvilinear features. The coder is composed of three main components: 1) a rate-distortion optimized beamlet-based representation, 2) a tree-based coding from a beamlet representation to a symbol stream, and 3) an entropy coder. This coder is named "JBEAM". Taking advantage of its multiscale property, we utilized tree-based coding to make it progressive. The derived coder has a low order of computational complexity. Simulations demonstrate an advantage over the state-of-the-art industrial standard: JBIG 2. A software package, which includes an implementation of JBEAM, is made available. Variations and potential improvements of this method will be discussed. This work may inspire more activities in this line of research, improving curve coding.
