Real-time 3D image registration for functional MRI.
Subject head movements are one of the main practical difficulties with brain functional MRI. A fast, accurate method for rotating and shifting a three-dimensional (3D) image using a shear factorization of the rotation matrix is described. Combined with gradient descent (repeated linearization) on a least squares objective function, 3D image realignment for small movements can be computed as rap...
متن کاملReal-time Registration for Image Mosaicing
This paper presents a real-time tracking technique for constructing spherical image mosaics from sequences of images. The main contribution is a tracking algorithm able to estimate in real-time camera rotations during the sequence, assuming that the optical center of the camera remain fixed. This assumption allows us to consider a sphere centered at this particular point and having its radius e...

متن کاملImage Registration for MRI
To register two images means to align them so that common features overlap and differences — for example, a tumor that has grown— are readily apparent. Being able to easily spot differences between two images is obviously very important in applications. This paper is an introduction to image registration as applied to medical imaging. We first define image registration, breaking the problem dow...
متن کاملA Novel Subsampling Method for 3D Multimodality Medical Image Registration Based on Mutual Information
Mutual information (MI) is a widely used similarity metric for multimodality image registration. However, it involves an extremely high computational time especially when it is applied to volume images. Moreover, its robustness is affected by existence of local maxima. The multi-resolution pyramid approaches have been proposed to speed up the registration process and increase the accuracy of th...
