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...
