“…Turning to the processing of real images of real documents, there is an extensive literature on the extraction of line structured data (eg Smith 1987, Black et al 1981 and on text and symbol recognition in diagrams (Lin et al 1985, Tudhope and Oldfield 1983, Bley 1984, Bunke 1982). …”

This paper assumes the situation where the existing drawing is to be re-utilized after a partial modification, and discusses a system, which can easily improve or modify with a high speed the characters and figures at the image level. First, the input drawing is segmented automatically and described in terms of the composing elements of the drawing, such as the character, the segment, the connecting point and the frame surrounding characters. structure description of the drawing, and no particular drawing is assumed, the method can be applied to various kinds of drawings. Then based on the description, the desired transformation is planned. Finally, based on the transformed description, the image is transformed. The proposed system features the following: (1) A versatile structure description is available; ( 2 ) two-stage transformation, i.e., the transformation at the description level and the transformation at the image level, is employed. This two-stage transformation makes possible the global transformation of the drawings, such that the frame surrounding the characters can be transformed according to the change of the character string length; and ( 3 ) the real-time image processing, such as extraction of the composing elements and image generation is realized by the data-flow processor.Since the description is the Among these problems, this paper discusses the drawing transformation system which can realize the processings (1) and (3).
