Abstract: A process for locating data fields on electronic images of complex-structured forms or documents. with the steps of: locating the approximate location of one field of data, of establishing the precise location of data based upon the approximate location, of establishing the approximate locations of a plurality of fields of data based upon the precisely located data, and of establishing the precise location of data for a plurality of the fields based upon the approximate locations.

Abstract: A process for validating groups of machine-read data fields in electronic images of documents with the steps of: A group of data fields, each containing an image, at least one perceived value, A relationship relating each field to the others, A of establishing whether the relationship is met, and of calculating a perceived value which fulfills the relationship, A of presenting the image, one of the perceived values and the calculated value for each of the fields to a human operator., A of allowing the human operator to edit one of the percieved values, and A of allowing the human operator to select one of the calculated values as being correct.
