Iris 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...
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 کاملInvariant Object Recognition Using Radon-based Transform
The properties of the Radon transform are used to derive the transformation invariant to translation, rotation and scaling. The invariant transformation involves translation compensation, angle representation and 1-D Fourier transform. The new object recognition method is studied experimentally in two domains, mammogram labels recognition and face recognition. For mammogram labels, the recognit...
متن کاملReal Time Human Activity Recognition System based on Radon Transform
A real time human activity recognition system based on Radon transform (RT), Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) is presented. RT improves low frequency components and PCA provide global representation of these low frequency components in few eigenvectors. The proposed technique computes radon projections in different directions to obtain directional featur...
متن کاملThe Iris Recognition Based on Curvelet Transform and Improved SVM
In order to increase the accurate rates of the iris recognition, this paper proposes iris recognition method based on the combination of second generation curvelet transform and the Support Vector Machine Category correction. The images collected from iris image acquisition system are identified. First, rotation correction of iris and spot removal are carried out for collecting iris images. The...
