Dissertação (Mestrado em Ciência da Computação) - Universidade Federal de Goiás, Goiânia, 2016.http://repositorio.bc.ufg.br/tede/handle/tede/6405In 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.application/pdfAcesso AbertoCBIRCADImagens médicasCBIRCADMedical imagesCIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAODissertação
