John D Peters, Hewitt D Crane, Eugenio Martinez Uriegas: Method and appartus for increasing resolution of digital color images using correlated decoding. SRI International, Townsend and Townsend and Crew, July 30, 1996: US05541653 (174 worldwide citation)

Color image compression and decompression is achieved by either spatially and chromatically multiplexing three digitized color planes, such as RGB (Red-Green-Blue) (22), into a digital array representative of a single digitized spatially- and chromatically-multiplexed plane (32, 813f) through use of ...

Hewitt D Crane, John D Peters, Eugenio Martinez Uriegas: Method and apparatus for decoding spatiochromatically multiplexed color images using predetermined coefficients. SRI International, Townsend and Townsend and Crew, May 4, 1999: US05901242 (104 worldwide citation)

Color image decoding is achieved by a simplified method of decoding a spatially and chromatically multiplexing image plane (32), such as a plane consisting of RGB (Red-Green-Blue) pixels (22) by performing a summation of pixels of all three colors in a neighborhood of a missing pixel. The decoding p ...

Hewitt D Crane, Daniel E Wolf, John S Ostrem: Identification by handwriting verification. Stanford Research Institute, Lindenberg Freilich et al, August 2, 1977: US04040010 (88 worldwide citation)

A person, who is to have his identity verified, first writes his signature or any other appropriate group of characters or symbols several times with a special pen which produces signals representative of the writing forces in the plane of the paper and the writing pressure. From these a number of d ...

Hewitt D Crane, John S Ostrem: Process and apparatus involving pattern recognition. Communication Intelligence Corporation, Townsend and Townsend, January 5, 1988: US04718102 (82 worldwide citation)

Processing of handwritten patterns, for example, inputting of complex characters, such as Kanji, into a word processor involves a balance between an algorithmic part and a disambiguation part. Application of routines uniformly during the algorithmic part deliberately results in confusion sets of cha ...

Hewitt D Crane, John S Ostrem: Complex pattern recognition method and system. Communication Intelligence Corporation, Townsend and Townsend, December 24, 1985: US04561105 (64 worldwide citation)

A method and system for recognizing complex patterns, such as Chinese characters (or Kanji), identifies patterns by stroke recognition using detailed information about stroke shape and specifically curvature characteristics. Written strokes are categorized into different specific stroke types and ar ...

Hewitt D Crane: Stabilized visual system. SRI International, Urban H Faubion, April 17, 1984: US04443075 (54 worldwide citation)

A stabilized visual system for directing a beam of energy, such as a laser beam, to a specific selected location in an eye and maintaining the beam in the selected location regardless of eye movements. The system employs a fundus illumination and monitoring device which illuminates the fundus of an ...

Hewitt D Crane, John S Ostrem: Confusion grouping of strokes in pattern recognition method and system. Communications Intelligence Corporation, Townsend & Townsend, February 25, 1986: US04573196 (45 worldwide citation)

A method and system for recognizing complex patterns, such as Chinese characters (Kanji), which may employ detailed information about an element and specifically curvature characteristics. Selected elements or strokes are grouped into confusion groups. Strokes under examination are categorized and a ...

Hewitt D Crane, Carroll M Steele: Double Purkinje eye tracker. SRI International, Urban H Faubion, September 1, 1981: US04287410 (31 worldwide citation)

An eye tracker measures the point in space on which the eye is fixated. An input mirror reflects an input image into the eye and directs the Purkinje images so formed in the eye back into the eye tracker mechanism. The images are gathered by a collimating objective and directed through focusing and ...
