A Study on Size Transformation for Dot Pattern by the 4-Direction Line Segmentation Algorithm

4방향 선분 분리법에 의한 도트 패턴의 크기 변화에 관한 연구

This paper proposes the four directional line segmentation method to transform the size of dot patterns such as character dot patterns, line drawings and so on, while maintaining the quality of original pattern. At the first, this method extracts three kinds of line segmentm, namely horizontal, vertical line and slant line, and then transforms dot patterns using the each rules which are appricable to each kind of extracted line segments. Our experimental results show that transformation of dot patterns can be succeed in good quality without implementing some kinds of smoothing processes, covering the continuous transforming ratio of 0.5 to N times.
