Resumo: | Otoliths are called "black box" because they are sources of biological information that can be applied to the evaluation and management of fish stocks. And, one of the ways to study them is from analysis of images. However, 2D images have already been extensively explored, despite losing information because otoliths are a 3D object. Thus, the present study aimed to apply computed tomography to analyze otoliths sagittae. From 15 configurations of the tomographic parameters, it was concluded that average voltages (70 and 80 kV) with aluminum filters with 0.5 mm thickness are optimal for the acquisition of tomographic images of otoliths. These images were then explored internally and externally, with applications in growth ring counts, ontogeny, species comparisons, and, in the future, layered segmentation using the density difference. In addition, internal cavities were found in individuals of the genus Thunnus. The curvature of the surface of the otoliths was also analyzed in order to test the capacity of discrimination between species, ontogenetic variation and as a tool of segmentation of sulcus acusticus. It was found that the Mean and RMS curvature attributes can be used as a unique signature by species, besides discerning peaks and valleys in the relief of otoliths. And, from this, relate its complexity to the metabolism of individuals, as a reflection of age. In addition, with 3D segmentation, it will be possible to describe not only the area of the sulcus, but also its depth and volume. Therefore, this thesis will serve as a basis for future studies of 3D image analysis of otoliths and some applications. |

E, uma das maneiras de estudá-los é a partir de análises de imagens. Entretanto, as imagens em 2D já foram exaustivamente exploradas, apesar de perderem informações devido os otólitos serem um objeto em 3D. Assim, o presente estudo objetivou em aplicar tomografia computadorizada para analisar otólitos sagittae. A partir de 15 configurações dos parâmetros tomográficos, concluiu-se que voltagens médias (70 e 80 kV) com filtro de alumínio com 0,5 mm de espessura são ótimos para a aquisição de imagens tomográficas de otólitos. Em seguida, estas imagens foram exploradas internamente e externamente, com aplicações em contagens de anéis de crescimento, ontogenia, comparação entre espécies e, futuramente, segmentação em camadas usando a diferença de densidades. Ademais, verificou-se a presença de cavidades internas nos indivíduos do gênero Thunnus. Também foi analisada a curvatura da superfície dos otólitos, afim de testar a capacidade de discriminação entre espécies, variação ontogenética e como ferramenta de segmentação do sulcus acusticus. Constatou-se que os atributos de curvatura Mean e RMS podem serem usados como assinatura única por espécie, além de discernir picos e vales no relevo dos otólitos. E, a partir disto, relacionar sua complexidade com o metabolismo dos indivíduos, como reflexo da idade. Além disso, com a segmentação em 3D será possível descrever não só a área do sulcus, mas também sua profundidade e volume. Portanto, esta tese servirá como base para estudos futuros de análise de imagens em 3D de otólitos e algumas aplicação.Submitted by Mario BC (mario@bc.ufrpe.br) on 2019-07-31T13:29:07Z No. of bitstreams: 1 Jonas Eloi de Vasconcelos Filho.pdf: 4779575 bytes, checksum: 478011721d09675217cc0fd9954cca75 (MD5)Made available in DSpace on 2019-07-31T13:29:07Z (GMT).
