Finding related functional neuroimaging volumes

Finn Årup Nielsen, Lars Kai Hansen

AbstractWe describe a content-based image retrieval technique for finding
related functional neuroimaging experiments by voxelization of sets of
stereotactic coordinates in Talairach space, comparing the volumes and
reporting related volumes in a sorted list. Voxelization is accomplished by convolving each coordinate with a Gaussian kernel. The scheme allows us to compare experiments represented as either lists of coordinates or volumes, and we introduce alternative entrances to databases by image-based indices constructed via novelty measures and singular value decomposition.
