Efficient Multimodal Registration Using Least-Squares

چکیده
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 Method to multimodal registration. By modeling rotation as linear approximation we are successful at finding the global optimal translation and intensity remapping, and local optimal angle.

Multimodal registration of MR images with a novel least-squares distance measure
In this work we evaluate a novel method for multi-modal image registration of MR images. The key feature of our approach is a new distance measure that allows for comparing modalities that are related by an arbitrary gray-value mapping. The novel measure is formulated as least square problem for minimizing the sum of squared differences of two images with respect to changing gray-values of one ...
متن کاملAutomated Multimodal Volume Registration based on Supervised 3D Anatomical Landmark Detection
We propose a new method for automatic 3D multimodal registration based on anatomical landmark detection. Landmark detectors are learned independantly in the two imaging modalities using Extremely Randomized Trees and multi-resolution voxel windows. A least-squares fitting algorithm is then used for rigid registration based on the landmark positions as predicted by these detectors in the two ima...
متن کاملNonrigid Registration Using Regularized Matching Weighted by Local Structure
We present a novel approach to nonrigid registration of volumetric multimodal medical data. We propose a new regularized template matching scheme, where arbitrary similarity measures can be embedded and the regularization imposes spatial coherence taking into account the quality of the matching according to an estimation of the local structure. We propose to use an efficient variation of weight...
متن کاملAn Efficient Mutual Information Optimizer for Multiresolution Image Registration
We propose a new optimizer in the context of multimodal image registration. The optimized criterion is the mutual information between the images to align. This criterion requires that their joint histogram be available. For its computation, we introduce differentiable and separable Parzen windows that satisfy the partition of unity. Along with a continuous model of the images based on splines, ...
متن کاملCoregistration of Pose Measurement Devices Using Nonlinear Least Squares Parameter Estimation
Multimodal visual haptic user interfaces can be made more effective by accurately colocating the workspaces of their components. We have developed a coregistration technique for pose measurement devices based on nonlinear least squares parameter estimation. A reduced quaternion parameterization is used for representing the orientation component of coordinate transformations, which avoids the nu...
