A web-based environment for shape analysis of fish otoliths. The AFORO database

6 pages, 3 figures. [EN] We present an automatic system for describing and identifying fish otolith shapes combining information technologies with modern advances in signal analysis. As a major novelty with respect to past studies the system includes wavelets (WT) and curvature space scale (CSS) ana...

Respecto a otros sistemas, éste presenta como principal novedad el uso de análisis de formas basados en la aplicación de wavelets (WT) y análisis de la curvatura a diferentes escalas (CSS). Estos análisis proporcionan información local de las características morfológicas del contorno externo del otolito de forma automática, facilitando la labor de identificación a no especialistas en morfología de otolitos. Una aplicación directa de este sistema facilitará la determinación del tamaño, la población y la especie en peces Teleósteos. Ambos, el sistema de análisis de formas y el catálogo de otolitos se implementan en la base de datos AFORO, que incluye actualmente, más de 1250 imágenes de alta resolución de otolitos pertenecientes a 292 especies y 94 familias de peces Teleósteos, procedentes básicamente del mar Mediterráneo y del océano Antártico This work has been supported by the Spanish MICYT TIC2000-0376-p4-04 project Peer reviewed Article in Journal/Newspaper Antarc* Antarctic Digital.CSIC (Spanish National Research Council) Alta Antarctic Scientia Marina 70 1 147 152
