Abstract
A method comprising receiving a candidate image, including a first field, a second field, a first data element, and a second data element. The processor receives a definition of first and second form zones. The processor evaluates the first data element to determine a first measure of a similarity and the second data element to determine a second measure of a similarity. The processor computes a similarity value indicative of an overall similarity, iteratively compares the overall similarity to a previous iteration, modifies the positions of the form zones, and repeats the evaluating and computing based on the modified positions until the computed similarity value meets a threshold.
