Abstract

The current application is directed to a method and system for automatically determining the sense orientation of regions of scanned-document images that include symbols and characters of languages that are not written as simple sequential strings of alphabetic characters. In one implementation, the sense-orientation method and system to which the current application is directed employs a relatively small set of orientation-marker characters that occur frequently in printed text and that lack rotational symmetry. In this implementation, text-character images within a region of a scanned-document image are compared to each of a set of orientation-marker patterns corresponding to orientation-marker characters in order to identify images corresponding to orientation-marker patterns in the text-containing region of the scanned-document image and to determine an overall sense orientation for the text-containing region of the scanned-document image based on the orientations of the identified orientation-marker patterns.

First claim

The invention claimed is:

1. An image processing system that determines an orientation for a text-containing region of an image, the image processing system comprising:
one or more processors;
one or more electronic memories;
one or more mass-storage devices;
an orientation-marker pattern set stored in one or more of the one or more electronic data storage devices, wherein the orientation-marker pattern set comprises two or more patterns corresponding to two or more consider…
