From: Rigid Registration of Renal Perfusion Images Using a Neurobiology-Based Visual Saliency Model
Difference images highlighting performance of our registration algorithm. Columns 1–3 show reference image, floating image, and difference image before registration. Columns 4–6 show difference images after registration using NMI, QMI1, and QMI2, respectively. Rows 1 and 2 show pairs of images belonging to different stages of contrast enhancement. Rows 3 and 4 show images where the reference-floating image pair was from either pre- or postcontrast stage.
