Problems solved by technology

However, in low-resolution images, singularities and fine details cannot be easily observed, thus, more easily identifiable wrinkles must play an important role in identification
However, from figure 2 As can be noticed in , only a small fraction of the surroundings are clear, the question is whether it provides enough uniqueness to reliably identify individuals in a large population

Embodiment Construction

[0056] The palmprint recognition method of the present invention includes three parts: 1) obtaining an individual's palmprint image; 2) analyzing the skin texture data according to the image; and 3) comparing the skin texture data with information stored in a database. Below, these steps will be described in more detail.

[0057] 1) Obtain the palmprint image of the individual

[0058] refer to image 3 , using a CCD camera in a known manner to obtain a low-resolution image of a part of the inner surface of the hand. In order to extract recognition data from images, hand features must be exploited to identify reproducible sub-images of the palm region. In a preferred embodiment, the gaps between the fingers are identified and used as parameters to construct a coordinate system in which the parameters defining the sub-images can be found. The preferred embodiment has six main steps, as described below.

[0059] refer to Figure 4 , the first step is to apply a low-pass fil...

Abstract

A method of palmprint identification includes analyzing an area from an image of a palm to obtain texture data for the skin surface with the area. The texture data is compared to reference information in a database to determine the identity of an individual. An apparatus for capturing an image of a palm includes an enclosure with a window in it, and an image sensor and light source disposed within the enclosure and arranged to capture an image through the window. Protuberances are provided on the surface. The protuberances are arranged to be in known juxtaposition to a hand suitably placed on the window for capture of an image that includes the palm area of the hand.

Description

technical field [0001] The present invention relates to biometric identification, and more particularly to a method of analyzing palm prints to identify individuals. The invention also relates to a device for capturing images of palm prints in order to identify individuals. Background technique [0002] Utilizing palmprint recognition as a method of personal identification is a new biometric technique replacing fingerprints. Known methods include analyzing palm prints to identify singularities, fine details and wrinkles in the palm print image. These known methods require as figure 1 High resolution images shown. This can be obtained through dyed palm prints. However, doing so is dirty and doesn't get real-time recognition. [0003] To overcome the problem of stained palmprints, some companies have developed high-resolution palmprint scanners and recognition systems. However, these devices for capturing high-resolution images are expensive and rely on high-performance ...
