Research Workshop 2009/01 - CAPES/COFECUB : Content-based Image Retrieval of Mammographies Using the IRMA Database

Abstract


This work aims at developing a content-based image retrieval (CBIR) system for mammographies using as pattern the breast density. The database used, from the IRMA project, provides images with the ground truth already set, in a way to facilitate the evaluation of the proposed system. This work focuses on the breast density characterization through the texture representation together with the reduction of the dimensionality of the feature vector. Two methods are proposed: MammoSVD (using the singular value decomposition - SVD) and MammoPCA (using the two dimensional principal component analysis - 2DPCA). Support vector machine (SVM) is used for the retrieval task.
