  • METHOD AND SYSTEM FOR MULTISPECTRAL PALMPRINT VERIFICATION
    Publication number: 20120194662
    Abstract: A method for palmprint verification of an individual that includes illuminating a palm of an individual with a plurality of spectral bands, collecting a plurality of palmprint images that are illuminated under the different spectral bands, locating a sub-image from each of the plurality of palmprint images, extracting palmprint feature maps from the sub-images, determining a palmprint matching score for each of the spectral bands based on the palmprint feature maps, computing a fused score by combining at least two of the palmprint matching scores under different spectral bands, without double-counting overlapping regions, and comparing the fused score with a threshold score from a database.

  • Method of multi-modal biometric recognition using hand-shape and palmprint
    Patent number: 8135181
    Abstract: The present invention relates to a method and system for a multimodal biometric system utilizing a single image to generate hand shape and palmprint features. The invention utilizes a digital camera, and incorporates feature subset selection algorithms to eliminate redundant data. The inventions, through the use of feature algorithm, successfully fuses the hand shape features and palmprint features at the features level.

  • Method of palm print identification
    Patent number: 7496214
    Abstract: A method of biometrics identification includes obtaining an image including a portion of a hand of an individual, analyzing the image to find one or more feature parameters defining different characteristics of the hand, and comparing the feature parameters with reference information in a database. The features parameters including a geometrical features parameter, a palm line features parameter or a palm texture features parameter.
