Gabor Wavelet for Feature Extraction in Iris Recognition

This documentation provides a comprehensive implementation of Gabor wavelet-based feature extraction specifically designed for iris recognition systems. Additionally, we include a robust iris normalization program that ensures recognition accuracy and consistency throughout the identification process.

Gabor wavelet feature extraction plays a critical role in iris recognition technology. Our implementation utilizes multi-scale and multi-orientation Gabor filters to capture distinctive texture patterns from iris images. The algorithm employs complex Gabor functions with adjustable parameters (frequency, orientation, bandwidth) to extract phase and amplitude information from localized iris regions. This approach effectively encodes the unique biometric features necessary for accurate identification. Feature extraction serves as the core component in iris recognition pipelines, enabling the distillation of essential information from vast image datasets.

The accompanying iris normalization program addresses variability issues caused by different acquisition conditions. Our implementation uses rubber-sheet model transformation to map the annular iris region from Cartesian to polar coordinates, compensating for pupil dilation variations and imaging angle differences. The normalization algorithm incorporates interpolation techniques to handle resolution inconsistencies and preprocessing steps to mitigate illumination variations and image quality disparities.

Both programs leverage state-of-the-art algorithms and optimization techniques to ensure efficient and precise iris recognition performance. The feature extraction module includes parallel processing capabilities for handling multiple filter banks, while the normalization component implements adaptive thresholding and contrast enhancement methods. We provide these implementations to support your iris recognition projects with industry-standard methodologies.
