Stochastic Optimization for Rigid Point Set Registration
In this paper we propose a new method for pairwise rigid point set registration. We pay special attention to noise robustness, outlier resistance and global optimal alignment. The problem of registering two point clouds in space is converted to a minimization of a nonlinear cost function. We propose a cost function that aims to reduce the impact of noise and outliers. Its definition is based on...
متن کاملNon-rigid Registration Using Morphons
The Morphon, a non-rigid registration method is presented and applied to a number of registration applications. The algorithm takes a protoype image (or volume) and morphs it into a target image using an iterative, multi-resolution technique. The deformation process is done in three steps: displacement estimation, deformation field accumulation and deformation. The framework could be described ...
متن کاملRigid Registration
Rigid registration is the process of identifying the correspondences between two overlapping shapes that were subject to a rigid transformation. Once the correspondences have been established, the underlying rigid transformation can be estimated in the weighted least squares sense with closed form solution. A correspondence is such a pair of points that while they are described in two different...
متن کاملCompensation of brain shift during surgery using non-rigid registration of MR and ultrasound images
Background: Surgery and accurate removal of the brain tumor in the operating room and after opening the scalp is one of the major challenges for neurosurgeons due to the removal of skull pressure and displacement and deformation of the brain tissue. This displacement of the brain changes the location of the tumor relative to the MR image taken preoperatively. Methods: This study, which is done...
متن کاملRigid point registration circuits
In 1996 Freeborough proposed a method for estimating target registration error (TRE) in the absence of ground truth. In his approach, a circuit of registrations is performed using the same registration method on multiple views of the same object: 1 to 2, 2 to 3, ..., NC –1 to NC , and NC to 1 where NC is at least three and the last registration completes the circuit. Any difference between the ...
