Gabor filter on iris

The texture features of a person’s iris image are sufficient to represent the uniqueness of each individual, so we extract the texture features of an iris image by 2D-Gabor filters with different scales and orientations [15]. 2D-Gabor function is a product of an elliptical Gaussian and a complex plane wave. It can be … See more LBP is a grayscale texture operator which characterizes the spatial structure of the local image texture. LBP has been widely used for figure prints and face recognitions for its ability of … See more In this paper, determination about their category is made by calculating the Bhattacharyya distance between the input and enrolled … See more WebAug 2, 2015 · This can be seen too when I combine all the filters (of all 5 scales and 9 orientations) in one image: Update: Adding the impulse response of the filter in spatial domain, as you can see there is an …

WebIn this paper, we propose an effective iris recognition algorithm which adopts a bank of Gabor filters combined with the estimated fractal dimension. After the preprocessing procedure, the normalized effective iris region is decomposed according to different frequency regions by the multi-channel Gabor filters. WebHowever, it is difficult to achieve high recognition accuracy when the Gabor filter or LBP is directly applied to iris texture representation. This paper presents an effective iris feature descriptor, which first uses 2D-Gabor filter to extract multi-orientation imaginary (MOI) feature, and then applies uniform LBP for region feature encoding. loan wolf zip forms https://katieandaaron.net

Web2. Prior work The most promising iris recognition approach is presented by Daugman [3]-[4] using 2D Gabor wavelets for encoding the iris. Wildes’s [6] has used the band-pass decomposition derived from application of Laplacian of Gaussian filters, implemented in the practice by the Laplacian Pyramid.

In document image processing, Gabor features are ideal for identifying the script of a word in a multilingual document. Gabor filters with different frequencies and with orientations in different directions have been used to localize and extract text-only regions from complex document images (both gray and colour), since text is rich in high frequency components, whereas pictures are relatively smooth in nature. It has also been applied for facial expression recognition Gabor …
