Daniel Curtis Gray - Niskayuna NY, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

G06K 9/40
H04N 9/04

US Classification:

382255, 34820799

Abstract:

An imaging system includes a positionable device configured to axially shift an image plane, wherein the image plane is generated from photons emanating from an object and passing through a lens, a detector plane positioned to receive the photons of the object that pass through the lens, and a computer programmed to characterize the lens as a mathematical function, acquire two or more elemental images of the object with the image plane of each elemental image at different axial positions with respect to the detector plane, determine a focused distance of the object from the lens, based on the characterization of the lens and based on the two or more elemental images acquired, and generate a depth map of the object based on the determined distance.

International Classification:

G06K 9/00

US Classification:

382124, 382126

Abstract:

A system and method for contactless multi-fingerprint collection is disclosed. The contactless multi-fingerprint collection system includes an imaging volume, a user interface configured to provide feedback to the subject regarding a proximity of a hand to a desired imaging location within the imaging volume, and at least one image capture device to capture images of each of the plurality of fingerprints at each of at least two different depths from the fingerprints. The contactless multi-fingerprint collection system also includes a processor coupled to the at least one image capture device that is programmed to generate a composite image and a contour map of each of the plurality of fingerprints from the images captured at the at least two different depths and generate a two-dimensional rolled equivalent image of each of the plurality of fingerprints from the composite image and the contour map.

Abstract:

A method of creating an article of manufacture is provided, which includes directing multiple laser beams to a single galvanometer; and dynamically repositioning the multiple laser beams in counterpart paths using the single galvanometer to shine the multiple laser beams on and melt a first powder material and, upon solidification of the melted first powder material, forming a first series of duplicate three dimensional structures, where each of the multiple laser beams is used to form at least one of the first series of duplicate three dimensional structures.

Abstract:

Methods and systems for autofocusing of an imaging system are presented. Provided is an imaging system and an optical interferometry system for generating one or more images corresponding to a target region in a subject. The method provides calibration information that identifies a focal position of the optical interferometry system corresponding to a determined focal position of the imaging system. A subsequent focal position of the imaging system is determined for generating a desired image corresponding to at least one of another target region in the subject and another position of the target region relative to the imaging system based on the calibration information.
