Fecha de publicación: | 14-may-2020 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Applied Sciences 10(10): 3408 (2020) | Resumen: | This work deals with the task of distinguishing between different Mediterranean demersal species of fish that share a remarkably similar form and that are also used for the evaluation of marine resources. The experts who are currently able to classify these types of species do so by considering only a segment of the contour of the fish, specifically its head, instead of using the entire silhouette of the animal. Based on this knowledge, a set of features to classify contour segments is presented to address both a binary and a multi-class classification problem. In addition to the difficulty present in successfully discriminating between very similar forms, we have the limitation of having small, unreliably labeled image data sets. The results obtained were comparable to those obtained by trained experts | Descripción: | 23 pages, 14 figures, 4 tables | Versión del editor: | https://doi.org/10.3390/app10103408 | URI: | http://hdl.handle.net/10261/212549 | DOI: | 10.3390/app10103408 | Identificadores: | doi: 10.3390/app10103408 e-issn: 2076-3417 |
