An msm coding of a binary image and an msm figure‐file system

Abstract

AbstractResearches on the coding and filing of such binary image data as versatile links of drawings or topographical maps have been conducted widely [5 ‐ 19]. The reasons for this activity are tied to the advances made in techniques for processing topographical information [1, 2], automatic drawing reading [3], and image datebases [4].These techniques are aimed at high‐density compressions in image coding, but especially at greater flexibility in figure reconstruction. Additionally, some of these techniques have found practical application in such commercial areas as image databases of topographical maps or drawings or visual communications by facsimile.However, these techniques are difficult when using coding image data to obtain such flexible image processings as skeletonization or border following of figures, the detection of width or branch points of line figures, or structural analysis of line or surface drawings. As a result, this paper proposes an MSM figure‐file system which codes a binary image via the MSM method and files it as a figure, and retrieves figure data from the file.
