Appl. No.:

11/456622

Inventors:

PETER Z. LO - LAKE FOREST CA, US
YING LUO - IRVINE CA, US

International Classification:

G06K 9/00

US Classification:

382124

Abstract:

Print image processing includes generating a first direction image and a multi-resolution hierarchy tree (MRT) having a plurality of direction measures, and adjusting at least one direction measure based on whether it is associated with a singularity area or a non-singularity area of the MRT, to output a final first direction image used for further print image processing. The MRT direction images include the first direction image having a highest resolution and at least one other direction image having a lower resolution. Each direction measure is determined from a direction measure, in a higher resolution direction image, which is selected based on image quality and distance from the boundary between print areas and non-print areas. Upon determining the final first direction image, a consistency measure can be computed and compared to a consistency metric and the method iteratively performed until the consistency measure satisfies the consistency metric.

International Classification:

G06K 9/00

US Classification:

382124

Abstract:

A method, apparatus and computer-readable storage element for determining quality of a print image, with the method including the steps of: estimating a centroid point of the physical print; setting dimensions of a quality computation frame based at least on a characteristic of the print image; centering the quality computation frame around the centroid point; determining, within the frame, a set of quality features; and computing a quality measure for the print image based on the set of quality features.

International Classification:

G06K 9/00

US Classification:

382124

Abstract:

A method for comparing a search print image comprising a first plurality of minutiae to a file print image comprising a second plurality of minutiae and the apparatus implementing the method is provided. The method includes the steps of: aligning the search and file print images; obtaining the first and second plurality of minutiae, a first plurality of pseudo-ridges generated from a first direction field of the search print image and a second plurality of pseudo-ridges generated from a second direction field of the file print image; for each aligning of the search and file print images, generating a pseudo-ridge score, and determining a minutiae matching score; and providing, based on the pseudo-ridge and minutiae matching scores, an output that indicates a level of similarity between the search and file print images.

International Classification:

G06K 9/00

US Classification:

382124

Abstract:

A method for level three feature extraction from a print image extracts features associated with a selected ridge segment using a gray-level image under the guidance of at least one binary image. The level three features are a sequence of vectors each corresponding to a different level three characteristic and each representing a sequence of values at selected points on a print image. The level three features are stored and used for level three matching of two prints. During the matching stage, ridge segments are correlated against each other by shifting or a dynamic programming method to determine a measure of similarity between the print images.

Abstract:

A method is performed in a print identification system to segment a non-segmented slap print image into its finger components. The method includes: receiving, for a hand, a non-segmented slap print image and a corresponding plurality of roll print images each corresponding to a different finger number; comparing the roll print images to the non-segmented slap print image to determine a number of mated minutiae areas on the non-segmented slap print image; detecting a number of print components from the non-segmented slap print image using the plurality of mated minutiae areas; and selecting a number of final print components from the detected print components and assigning finger numbers to the final print components, using the plurality of mated minutiae areas.

Abstract:

A lighting fixture lighter includes a frame body including a light transmitting window, a flame generator, and an illumination fixture built-in with the lighter for generating illumination light for illumination purpose. The illumination fixture includes a power source, a light source unit supported within a light compartment and aligning with the light transmitting window, and a light button to activate the light source unit for generating an illumination light, so that the illumination light is emitted out of the light transmitting window for illumination purpose. In order to enhance the light intensity of the light source unit, a light reflector is further provided within the light compartment for reflecting the illumination light from the light source unit, such that the lighter not only provides the traditional ignition function, but also provides an added on illumination function in the single compact lighter housing.
