Filed:

Dec 30, 2004

Appl. No.:

11/027846

Inventors:

Hrishikesh Aradhye - Mountain View CA, US
Gregory K. Myers - San Francisco CA, US

Assignee:

SRI International - Menlo Park CA

International Classification:

G06K 9/18
G06K 9/00
G06K 9/40

US Classification:

382182, 382105, 382154

Abstract:

An apparatus and a concomitant method for rectification and recognition of symbols (e. g. , to correct for the effects of perspective distortion, rotation and/or scale) in images of three-dimensional scenes is provided. The present method locates a reference region lying in a common plane with a symbol to be recognized, where the reference region represents an image of a planar object having assumed (e. g. , known or standard) geometry and dimensions, along with at least four easily detectable correspondence points within that geometry. An image of the common plane is then rectified in three dimensions in accordance with the assumed dimensions of the reference region in order to produce a transformed (e. g. , rectified) image of the symbol, which is significantly easier to recognize than the original imaged appearance of the symbol using existing recognition methods.

Abstract:

A method and apparatus are provided for person identification. In one embodiment, a method for identifying an individual includes obtaining at least one image of the individual, where the image depicts at least a portion of the individual's hair, comparing the visual characteristics of the individual's hair to the visual characteristics of imaged hair in one or more stored images, and identifying the individual based on the comparison.
