Document boundary analysis

A method comprising:

• obtaining, using one or more processors, at least one image of a document;
• obtaining, using the one or more processors, an edge domain representation of a first portion of the document;
• comparing, using the one or more processors, the edge domain representation of the first portion of the document to an edge domain representation of a corresponding portion of one or more valid document instances, wherein the comparison identifies one or more of an absence of an expected edge, a presence of an unexpected edge, and a discontinuity of an expected edge;
• and
• modifying, using one or more processors, a likelihood that the document is accepted as valid, or rejected as invalid, based on the comparison of the edge domain representations associated with the document and corresponding portion associated with one or more valid document instances.
