| Abstract: | An improvement to a method of extracting line and region information from technical drawings is presented. A scheme for compressing this information as it is being found is also given. The encoding scheme is based on a combination of run-length codes, direction chain codes, and Huffman codes. It is efficient, requires minimal storage, and achieves favorable compression ratios. Experimental results from four typical line drawings are presented. |
