Abstract
A simplification method for line drawings is proposed. The proposed method is possible to keep significant features of the object. It is well known that natural shapes, such as shoreline and clouds, have statistical self-similarity. The fractal dimension is one of the characteristics of the object which have self-similarity, so that we have already proposed simplification method using it as index. This method have achieved to simplify the object with remaining features of them by extracting significant points from the object. However, this method cannot distinguish the projected parts from curved parts, which is important in image analysis. Therefore, this paper proposes feature analysis method which can distinguish projected parts from curved parts. It is possible to simplify the object with satisfying wider demand by applying this proposed method.
