1. A method for creating a page template corresponding to a form for use in a mark recognition system, the method comprising:
identifying at least one path of traversal across a form;
identifying a set of reference marks wherein the set of reference marks defines a frame of reference for a page and matches the page to the template;
for each path of the identified at least one path of traversal, detecting edge transitions along said path, and defining an edge summary using the detected edge transitions; and
creating a page template using the edge summary for each of the paths of traversal across the form.
2. The method of claim 1, wherein identifying at least one path of traversal across a form includes identifying one or more straight lines traversing the form.
3. The method of claim 1, wherein the paths of traversal are defined by crossing horizontal and vertical lines.
4. The method of claim 1, wherein detecting edge transitions includes identifying a light-to-dark transition.
5. The method of claim 4, wherein the light-to-dark transition identifies the beginning of a mark.
6. The method of claim 1, wherein detecting edge transitions includes identifying a dark-to-light transition identifying the end of a mark.
7. The method of claim 1, wherein the page template includes an edge summary and a location for each of the identified at least one paths of traversal.
8. A method for recognizing a mark on a form in a mark recognition system, the method comprising:
recognizing a set of reference marks on a page, wherein the set of reference marks defines frame of reference for the page and matches the page to a template;
determining a projection to transform between the frame of reference for the page and a frame of reference for the template utilizing coordinates of said reference marks, where the template includes one or more targets for mark recognition;
adjusting location of imperfectly captured marks;
for each target of the one or more targets for mark recognition, search within a region to determine if a mark is present at such target, using the projection to transform between target locations in the template frame of reference and corresponding locations in the page frame of reference, and recording the result of the search.
9. The method of claim 8, wherein determining if a mark is present at such target includes authenticating such target by applying criteria to evaluate the extent of a match.
10. The method of claim 8, further comprising excluding pre-printed marks defined by the template.
The claims below are in addition to those above.
