U.S. Pat. No. 5,251,271 to Fling issued Oct. 5, 1993 discloses a method for registering digitized multi-plane color images. The method designates one plane as the reference plane and registers each of the other warped planes with the reference plane. Each plane comprises pixels representing luminosity values having scalar x and y coordinates representing positions in the horizontal and vertical directions, respectively, of the plane. The planes are divided into regions. Correlation values are calculated for regions within the divisional region of the reference plane with a plurality of regions offset from the corresponding warped divisional region. A warp error value is calculated for each pixel of each divisional region as a function of the scalar offset. The warp error values are interpolated and added to the current position of each pixel of the warped plane.
Separate processing of various types of data contained in a document is disclosed in U.S. Pat. No. 5,060,980 to Johnson et al. issued Oct. 29, 1991 which describes a xe2x80x9cformxe2x80x9d that includes user modifiable fields and an encoded description of the location, size, type, etc. of the fields to allow for direct programming of a form interpreter. Other information including the processing of the form, encoded data, etc. may be included in the encoded information. A system for creating forms carrying an encoded description of selected attributes of the fields includes means for selecting or creating fields and locating the fields on a form while generating, substantially simultaneously, the encoded description of the selected attributes. A form composer then allows merging of the form and its encoded description for printing or electronic transmission. A system for reading such forms includes a scanner, decoding device, and processor. By reading such forms, data may be entered into or recalled from a data processing system, or a form interpreter may be programmed, locally or remotely, for subsequent handling of forms.

Each plane comprises pixels representing luminosity values having scalar x and y organize representing positions in the horizontal and erect direction, respectively, of the plane. The planes are divided into area. correlation coefficient values are calculated for regions within the divisional area of the reference plane with a plurality of regions offset from the corresponding heave divisional region. A warp error value is calculated for each pixel of each divisional area as a function of the scalar outgrowth.
