Location of title and author regions in document images based on the Delaunay triangulation

摘要

Automatic title and author location can be a crucial step in journal document image processing systems. This paper presents a Delaunay triangulation-based method for identification of title and author areas in a technical document image. The positions and alignments of small text line regions are measured by different triangle groups and the character stroke widths are calculated from the constrained Delaunay triangulation. The rules defining spatial features and font attributes of the title and author region are applied to single line text regions to extract the title and author regions. Our experiment results show that the proposed method is effective.
