Abstract:
|
This paper analyzes the characteristics of an
experimental otolith retrieval system based on image contours
described with Elliptical Fourier Descriptors (EFD). Otoliths
are found in the inner ear of fish. Their shape can be analyzed
to determine sex, age, populations and species, and thus they
can provide necessary and relevant information for ecological
studies. The system we propose was tested by identifying three
different species, Engraulis encrasicolus from the family
Engraulidae, Pomadasys incisus from the family Haemulidae,
and two populations of the species Merluccius merluccius (from
Catalonia and Galicia) from the family Merlucciidae. We focus
on the search engine, experimenting with two cases and
analyzing the feature selection obtained with the EFD
coefficients. |
