Multimodal registration is a challenging problem in visual computing, commonly faced during medical image-guided interventions, data fusion and 3D object retrieval. The main challenge of multimodal finding accurate correspondence between modalities, since different modalities do not exhibit the same characteristics. This paper explores how coherence can be utilized for task registration. A nove...

When it comes to multimodal image registration, mutual information (MI) seems to hold the biggest market share. However, MI has a number of serious flaws, not the least of which is the quantization effect caused by histogram binning. We propose a novel registration method that, like MI, is motivated by the distribution of points in the joint intensity scatter plot (JISP). However, we avoid the ...

Magnet Resonance Angiography (MRA) can be used to register MR images of other types (e.g. functional MRI) acquired in the same imaging session as the angiogram since blood vessels are spatially closely confined features. This is only possible if MRA delivers reliable, reproducible images and does not show major random distortions. Therefore, we examine the reliability of MRA over subsequent sca...

In the context of thoracic CT-PET volume registration, we present a novel method to incorporate a breathing model in a non-linear registration procedure, guaranteeing physiologically plausible deformations. The approach also accounts for the rigid motions of lung tumors during breathing. We performed a set of registration experiments on one healthy and four pathological data sets. Initial resul...

The sum of squared differences (SSD) cost function has generally been overlooked for multimodal registration problems. More recently, methods that employ SSD have been developed to efficiently evaluate the global optimal shift and intensity remapping. However, these methods estimate translations and not rotations. In this paper we propose a method to extend the efficiency of the Least Squares M...
