Mammogram iterative pompeiu-hausdorff registration algorithm

Accurate mammogram registration is vital to future breast cancer research. In order to detect changes over time and/or bilateral asymmetry, computer aided detection algorithms must first be able to accurately align two mammogram images. The Mammogram Iterative Pompeiu-Hausdorff Registration Algorithm (MIPHRA) is a novel process designed to accurately register two mammogram images. MIPHRA is built upon a new technique for efficiently minimizing the Pompeiu-Hausdorff distance between two images (or point sets) over rigid body motion. A recent study comprised of 100 bilateral mammogram pairs revealed that MIPHRA offers increased accuracy and efficiency over current rigid-body mammogram registration techniques, such as mutual information.
