ABSTRACT:
A process for determining an orientation of a binary image includes segmentation of the image into many square regions. Orientations of the individual regions that are determined to be textual squares allow local variations of the binary image to establish an overall orientation for the binary image. The process iteratively groups and consolidates the individual regions into successively larger and larger regions. An orientation for particular ones of the larger regions is determined by a single mode of the various composite modes of the particular one regions having the greatest weight. After all the regions have been consolidated in this fashion, the process uses the orientation of the single consolidated region as the orientation of the binary image.
