]]>Abstract
Functional data analysis has been a novel option for representing images, since the continuous nature of images is preserved. Image representation using functional data provides significant advantages, being the appreciable reduction of the dimensionality one of the most significant. This paper gives a detailed description of the entire imaging process using the proposed approach. As an example, the representation of iris images through functional data for recognition tasks was used. The paper presents experiments and results of applying this approach to the recognition of iris images, demonstrating its effectiveness.
Keywords: Functional data analysis, Zernike bases, biometric image recognition.
Resumen
El análisis de datos funcionales ha sido una opción novedosa para la representación de imágenes, ya que su naturaleza continua se conserva. La representación de imágenes usando datos funcionales proporciona muchas ventajas, donde una de las más significativas es la reducción apreciable de la dimensión de los datos. En este trabajo se propone una descripción detallada de todo el proceso de representación de imágenes mediante el enfoque propuesto. Además, la representación de las imágenes del iris por medio de los datos funcionales para tareas de reconocimiento, se utilizó como un ejemplo. El artículo presenta algunos experimentos y resultados de la aplicación de este enfoque para el reconocimiento de imágenes del iris, lo que demuestra la eficacia de la misma.
Palabras clave: Análisis de datos funcionales, bases de Zernike, reconocimiento de imágenes biométricas.
