Resumo: In order to improve the diagnostic process several research centers have focused on the development of information systems applying powerful techniques of computer-aided diagnosis (CAD). In this context, the creation of content-based image retrieval (CBIR) is an important step in developing an efficient CAD system. This work proposes the validation of recovery with a hybrid CBIR method based on 2D medical images. The results of the techniques applied, indicate a hit rate of 90.25% and indicate a gain of 35% in the performance of techniques, that is, the time search and retrieval of images, paving the way for the development of information systems more efficient to build support generic diagnostic systems.

This work proposes the validation of recovery with a hybrid CBIR method based on 2D medical images.

Neste contexto, a criação de métodos de recuperação de imagens baseado em conteúdo (Content-based image retrieval - CBIR) é um passo importante para desenvolver um sistema CAD eficiente. Este trabalho propõe a validação de técnicas de recuperação com um método híbrido CBIR baseado em imagens médicas 2D. Os resultados das técnicas aplicadas, indicam uma taxa de acerto de 90,25% e ainda indicam um ganho de 35% no desempenho das técnicas, isto é, no tempo de busca e recuperação das imagens, abrindo caminho para o desenvolvimento de sistemas de informação mais eficientes para construção de sistemas de apoio ao diagnóstico genéricos.Submitted by Cássia Santos (cassia.bcufg@gmail.com) on 2016-10-17T13:34:17Z No. of bitstreams: 2 Dissertação - Elias Borges Macena Junior - 2016.pdf: 9321304 bytes, checksum: ca477b8a1eeb56b690f41c443b0ca638 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Jaqueline Silva (jtas29@gmail.com) on 2016-10-17T17:17:50Z (GMT) No. of bitstreams: 2 Dissertação - Elias Borges Macena Junior - 2016.pdf: 9321304 bytes, checksum: ca477b8a1eeb56b690f41c443b0ca638 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2016-10-17T17:17:50Z (GMT).
