%X Freehand shape is an efficient way for conveying and expressing human ideas.The key point for understanding the drawers' ideas is extracting the graphics primitives drawn on paper.By employing a hierarchical approach to extract the graphics primitives from images,this paper proposed an off-line recognition method for graphics primitives(line segment,arc,circle and ellipse).Firstly,described the image as a set of midline pixels,from which extracted line segments,and furthermore,broke line segments up and for...
