Elastic registration of x-ray mammograms and three-dimensional magnetic resonance imaging data.

abstract：:A long-standing challenge of content-based image retrieval (CBIR) systems is the definition of a suitable distance function to measure the similarity between images in an application context which complies with the human perception of similarity. In this paper, we present a new family of distance functions, called att...
