: 3D translational motion estimation from 2D displacements

چکیده
Recovering 3-D motion parameters from 2-D displacements is a di cult task, given the in uence of noise contained in these data, which correspond at best to a crude approximation of the real motion eld. The need for stability of the system of equations to solve is therefore essential. In this paper, we present a novel method based on an unbiased estimator that aims at enhancing this stability and strongly reduces the in uence of noise contamination. Experimental results using synthetic and real optical ows are presented to demonstrate the e ectiveness of our method in comparison to a set of selected methods.

Recovery of Ego-Motion Using Region Alignment
A method for computing the 3D camera motion (the egomotion) in a static scene is described, where initially a detected 2D motion between two frames is used to align corresponding image regions. We prove that such a 2D registration removes all effects of camera rotation, even for those image regions that remain misaligned. The resulting residual parallax displacement field between the two region...
متن کامل2D-3D Block Matching
This Master thesis deals with an approach for 2D-3D pose estimation, which relies on texture information on the surface mesh of an object model. The textured surface mesh is projected in a virtual image, and a block matching algorithm is employed to determine correspondences between midpoints of surface patches to the image data. To facilitate this purpose, the block matching algorithm needs to...
متن کاملRetrieving Three Dimensional Displacements of InSAR Through Regularized Least Squares Variance Component Estimation
Measuring the 3D displacement fields provide essential information regarding the Earth crust interaction and the mantle rheology. The interferometric synthetic aperture radar (InSAR) has an appropriate capability in revealing the displacements of the Earth’s crust. Although, it measures the real 3D displacements in the line of sight (LOS) direction. The 3D displacement vectors can be retrieved ...
متن کاملModel-based 3D Tracking of Cardiac Motion in HARP Images
We present an automated method for tracking 3D motion in planar tagged MRI. First, displacement between successive 2D image frames is estimated from their local phase, also known as HARP. The displacement estimates then drive a 3D finite element model which tracks systolic motion. The 3D model allows for 1) estimating 3D motion from niultiple 2D tagged images and 2) for regularizing the phase e...
متن کاملMotion Trajectories For Ultrasound Displacement Quantification
We present a robust methodology to quantify displacements in musculoskeletal ultrasound sequences. This paper extends the principles of 2D interframe displacements produced by our earlier work using hierarchical variable block size matching, to quantify displacement trajectories. We provide novel solutions for probe motion, quantification of objects moving in the 3D volume traversing the 2D pla...
