| Abstract(in English) | We proposed a CYK based two-dimensional parsing method for directly detecting a line pattern in a noisy picture according to a context free grammar (CFG) model. The time and spatial complexities of its basic algorithm amount to Ο(Ν^6) and Ο(ΜΝ^4), respectively, for Ν×Ν input image and Μ symbols Model. In this paper we investigate several improvements for efficiency enhancements. They include (1) the analyzed data limitation by removing background area from the image, (2) the symbol driven limitations for line tracing and rule application, (3) the shared parsing table among symbols. Significant efficiency improvement of the proposed algorithm was observed through experiments. |
