A Method for 3D Image Retrieval

Abstract

The usefulness of 3D image retrieval paradigm is evaluated in the context of neurological research using 265 high resolution MRI-T1 brain datasets of healthy controls. The method is based on multi-sort co-occurrence descriptors. It is shown that the approach can be used for localization of specific brain regions (mean deviation of 2.4 mm for searching anterior/posterior commissures), retrieval subjects from different age groups (more than 90% correct in top-10 for retrieval of young and aged subjects), and distinguishing very weak differences associated with gender (62% correct in top-10 query results on 210 young healthy subjects).
