A feature extracting method converts an image data of an input line drawing into a graph representation and recognizes the input line drawing by use of the graph representation. The feature extracting method comprises a first step of equally dividing the image data of the input line drawing into meshes, a second step of obtaining a cell by integrating one or more meshes, and a third step of recognizing a cell pattern for each of cells which are obtained so as to form a graph in correspondence with each of the cells.
