A New Method for Iris Recognition Based on Contourlet Transform and Non Linear Approximation Coefficients
In different methods of Biometrics, recognition by iris images in recent years has been taken into consideration by researchers as one of the common methods of identification like passwords, credit cards or keys. Iris recognition a new biometric technology has great advantages such as variability, stability and security. In this paper we propose a new feature extraction method for iris recognit...
متن کاملContourlet Transform for Iris Image Segmentation
The aim of this paper is improving the iris segmentation with the Contourlet transform. At first iris segmentation performed by canny edge detector and Hough Transform. By this approach some images don’t segmented properly, so we want to find a way to correct the image segmentation failures. Before applying edge detector, Contourlet transform applied for image denoising. By this approach, %100 ...
متن کاملA Fast Localization and Feature Extraction Method Based on Wavelet Transform in Iris Recognition
With an increasing emphasis on security, automated personal identification based on biometrics has been receiving extensive attention. Iris recognition, as an emerging biometric recognition approach, is becoming a very active topic in both research and practical applications. In general, a typical iris recognition system includes iris imaging, iris liveness detection, and recognition. This rese...
متن کاملComparative Insight in to Wavelet Transform and Contourlet Transform for Iris Recognition Systems
Human iris recognition is one of the prominent type of biometric identification system. Iris recognition systems use texture modeling for the segmentation and classification of iris images. Texture modeling is an active research field and different techniques have been exhaustively studied for this purpose, including wavelet transform. However, due to the limited capability for capturing direct...
متن کاملIris Recognition based on Radon Transform
The iris image has been viewed as a texture image. Radon transform has been used for detecting essential lines and curves present in iris texturesThe Radon transformed iris image is divided into distinct non-overlapping blocks. The size of a block is chosen such that sufficient information must appear in it. Then the average variance in each block is computed. The variance of the pixel intensit...
