Claim 13:
14. The computer program product as recited in claim 1, wherein determining the one or more logical relationships between the non-textual elements comprises:
identifying candidate rectangular elements within the one or more images; and
filtering the candidate rectangular elements to exclude one or more of the candidate rectangular elements that satisfy at least one of the following criteria:
a difference in a side line length for any given set of corresponding horizontal lines within a pair of adjoining candidate rectangular elements is less than a minimum horizontal line length threshold, and a horizontally oriented difference line of one of the adjoining candidate rectangular elements overlaps with a top boundary and/or a bottom boundary of another candidate rectangular element;
the difference in the side line length for any given set of corresponding vertical lines within a pair of adjoining candidate rectangular elements is less than a minimum vertical line length threshold, and a vertically oriented difference line of one of the adjoining candidate rectangular elements overlaps with a left boundary and/or a right boundary of another candidate rectangular element;
a border of the candidate rectangular element is located within a predetermined threshold distance, along a direction perpendicular to the longitudinal axis of the border, of a nearest second candidate rectangular element border;
one or more borders of the candidate rectangular element is located within a threshold proximity of a root border of a root container of the one or more images;
horizontally adjacent candidate rectangular elements do not overlap; and/or
the candidate rectangular element conflicts with another candidate rectangular element.
