边界跟踪并行处理的新方法

New method of parallel processing for boundary tracking

针对边界跟踪的复杂问题，首次提出了边界跟踪问题的数据并行、处理并行的系统并行处理模式。在图像预处理中，实时地实现了Ｒｏｂｅｒｔｓ算子和图像分割；在图像跟踪中，实时地实现了链码结构的边界跟踪；在硬件结构中，采用了功能流水线的方法，实现了图像采集、图像预处理、边界跟踪的综合集成，由此实现了边界的高速跟踪。论述了并行数据存取原理，介绍了边界跟踪系统的整体结构以及并行预处理、并行跟踪的方法，给出了边界跟踪的实例。

Aiming at the complex question of edge tracing,this paper presents a new system parallel mode with parallel data and parallel processing. In image preprocessing the new system realizes Robeters operator and image segmentation in real time. In image tracing this system realizes the chain code edge tracing in real time. In hardware structure this system adopts the function pipeline methods to integrate the image capture, preprocessing and edge tracing into one system, and realizes high speed edge tracing. This paper discusses the theory of paral- lel data accessing, introduces the whole system structure and the method of parallel preprocessing and edge trac- ing, and also offers some examples of edge tracing.
