An Efficient Algorithm for iris pattern Recognition using 2D Gabor Wavelet

Wavelet analysis have received significant attention because their multi-resolution decomposition allows efficient image analysis. It is widely used for varied applications such as noise reduction, and data compression, etc. In this paper we have introduced and applied the concept of 2 dimensional Gabor wavelet transform to Biometric Iris recognition system. The application of this transform in encoding the iris image for pa ....etc

Abstract
This paper describes a fast face identification methodwith Gabor filters. Two efforts are made to achieve the acceptableprocessing speed: 1) we design the optimal Gaborfilters with the arrangement theory that uses a few directionsand layers. 2) The transformation with Gabor filters(as called Gabor transformation) is only done over the regionsaround the facial feature points, not the whole inputimage. The facial feature points extraction is performed bydetecting the facial organ regions with color informationand edge informatio ....etc

ABSTRACT
We present a system for the visualization of an important signal processing technique- a Gabor Filter bank’s response to an image. To do this, one must overcome the problem that no multi-dimensional space can be shown in a a single, static graph. We use an interactive widget to change the visible range of the projected dimensions, and additional graphics which summarize the responses in the projected dimensions. Thus, though we view this four-dimensional space through 2-dimensional projections, we allow the user to understa ....etc

An efficient algorithm for iris pattern recognition using 2D Gabor wavelet transformation in Matlab




An introduction:

A dictionary defines image as a “reproduction or representation of the form of a person or
thing”. The inherent association of a human with the visual senses, predisposes one to
conceive an image as a stimulus on the retina of the eye, in which case the mechanism of
optics govern the image formation resulting in continuos range, mult ....etc

Abstract.
The present paper presents a model for
texture discrimination based on Gabor functions. In
this model the Gabor power spectrum of the micropatterns
corresponding to different textures is calculated.
A function that measures the difference between
the spectrum of two micropatterns is introduced
and its values are correlated with human performance
in preattentive detection tasks. In addition, a two stage
algorithm for texture segregation is presented. In the
first stage the input image is transformed via Gabor
filter ....etc
