Multimodal Registration via Spatial-Context Mutual Information
We propose a method to efficiently compute mutual information between high-dimensional distributions of image patches. This in turn is used to perform accurate registration of images captured under different modalities, while exploiting their local structure otherwise missed in traditional mutual information definition. We achieve this by organizing the space of image patches into orbits under ...
متن کامل1 Multimodal and Multiband Image Registration Using Mutual Information
In this paper, we present a novel histogram based method for estimating and maximising mutual information (MI) between two multi-modal and possibly multi-banded signals. Histogram based estimation methods are a common means for estimating the MI between two signals and the derivative of MI with respect to these signals. However, they do not scale well towards higher dimensions of the signals in...

متن کاملMultimodal unbiased image matching via mutual information
In the past decade, information theory has been studied extensively in computational imaging. In particular, image matching by maximizing mutual information has been shown to yield good results in multimodal image registration. However, there have been few rigorous studies to date that investigate the statistical aspect of the resulting deformation fields. Different regularization techniques ha...
متن کاملElastic registration of multimodal prostate MRI and histology via multiattribute combined mutual information.
PURPOSE By performing registration of preoperative multiprotocol in vivo magnetic resonance (MR) images of the prostate with corresponding whole-mount histology (WMH) sections from postoperative radical prostatectomy specimens, an accurate estimate of the spatial extent of prostate cancer (CaP) on in vivo MR imaging (MRI) can be retrospectively established. This could allow for definition of qu...
