Systems and methods automatically generate a model of a form or other document and identify the form or other document. In one aspect, a system and method normalize an image of a document and identify the relative positions of vertical and horizontal lines in the normalized image. The relative positions of vertical and horizontal lines of the normalized image are the model of the document image. The model may be stored in a record, such as an array. The system and method compare the relative positions of vertical and horizontal lines of the model to the relative positions of vertical and horizontal lines of other models to identify a matching model.
