Machining Region Boundary Extraction Algorithm Based on Z-map Model
基于Z-map模型的加工区域边界抽取算法研究

For redusing the region boundary extraction algorithm complexity, in this study, Z-map model to binary image with value-range is transformed, then region problem is extracted from binary image. Via scanning Row and run, right and left node of run is connected by its relationship between Row,then the loop is constructed by foregoing connection and extract region boundary. According to the relationship of the run's connection, resume the region boundary information is resumed completely. The time complexity of extraction algorithm is O(n), while n is the number of run. At last, the relation between the time consuming of the algorithm and the number of run, row and column were provided, while comparison of this arithmetic and before was also given.
