A method for processing a plurality of input images containing variable content that is filled into respective, fixed templates. The method includes comparing the images to collect a group of the images having a high degree of similarity therebetween, and combining the images in the group so as to distinguish the variable content from a fixed portion common to a preponderant number of the images in the group. The fixed portion is processed to reconstruct the fixed template that is common to at least some of the images among the preponderant number, and information is extracted from the images using the reconstructed template.

Automatic template and field definition in form processing

In an image processing system for processing filled in forms, a method and system are disclosed for removing the fixed part or template of a form without altering the variable part or information filled into the form. Whenever the variable part overlaps a fixed part of a filled in form a straightforward removal of the template creates gaps in the information characters making them unrecognizable by Optical Character Recognition (OCR) Software. This problem is overcome, according to the invention, by scanning a filled in form using any appropriate optical device capable of capturing images made of gray level pixels. First the fixed template pixels and the variable information pixels are separated from each other based on pixel position. Thereafter, the fixed and variable part populations of pixels are further analyzed so that gaps can be filled by moving pixels from the fixed part to the variable part on the basis of their gray levels thus, permitting to filling the gaps.

Method and system for dropping template from a filled in image

Image processing apparatus is disclosed for splitting, for subsequent storage or processing by OCR apparatus, character images in digital form comprising connected characters, the image processing apparatus extracts an image skeleton from an input image and represents the topology of the image skeleton in a first data structure; generates, from the first data structure, second data structures representing the topologies of the results of possible splits of the input image skeleton; evaluates the second data structures and selects one of the possible splits to thereby split the input image.

Method and apparatus for splitting connected characters into component

A data entry system generates an electronically stored coded representation of a character sequence from one or more electronically stored document images. The system comprising optical character recognition logic for generating, from the document image or images, character data specifying one of a plurality of possible character values for corresponding segments of the document images. The system also has an interactive display means for generating and sequentially displaying, one or more types of composite image, each composite image comprising segments of the document image or images arranged according to the character data, and a correction mechanism responsive to a user input operation to enable the operator to correct the character data associated with displayed segments.
