3D motion estimation based on pitch and azimuth from respective camera and laser rangefinder sensing
(11/03/2013)
This paper proposes a new method to estimate the 3D motion of a vehicle based on car-like structured motion model using an omnidirectional camera and a laser rangefinder. In recent years, motion estimation using vision ...
A Novel Hybrid Approach for Fast Block Based Motion Estimation
The current work presents a novel hybrid approach for motion estimation of various video sequences with a purpose to speed up the entire process without affecting the accuracy. The method integrates the dynamic Zero motion ...
Bayesian Estimation of Turbulent Motion
(IEEE Computer Society, 2013-04)
Based on physical laws describing the multiscale structure of turbulent flows, this paper proposes a regularizer for fluid motion estimation from an image sequence. Regularization is achieved by imposing some scale invariance ...
2D Instantaneous Frequency-based Method for Motion Estimation using Total Variation
(Institute of Electrical and Electronics Engineers, 2014-12)
We present a first approach to a new method to compute the motion estimation in digital videos using the two-dimensional instantaneous frequency information computed using amplitude-modulation frequency-modulation (AM-FM) ...
2D amplitude-modulation frequency-modulation - based method for motion estimation
(Institute of Electrical and Electronics Engineers, 2015-02)
We present a new approach to compute the motion estimation in digital videos using 2D amplitude-modulation frequency-modulation (AM-FM) methods. The optical flow vectors are computed using an iteratively reweighted norm ...
Self-supervised learning-based diffeomorphic non-rigid motion estimation for fast motion-compensated coronary MR angiography
(ELSEVIER SCIENCE INC, 2022)
Purpose: To accelerate non-rigid motion corrected coronary MR angiography (CMRA) reconstruction by developing a deep learning based non-rigid motion estimation network and combining this with an efficient implementation ...
A Review on Block Matching Motion Estimation and Automata Theory based Approaches for Fractal Coding
Fractal compression is the lossy compression technique in the field of gray/color image and video compression. It gives high compression ratio, better image quality with fast decoding time but improvement in encoding time ...
Motion-based wave estimation: Small-scale tests with a crane-barge model
(ELSEVIER SCI LTDOXFORD, 2012)
This paper provides additional validation to the problem of estimating wave spectra based on the first-order motions of a moored vessel. Prior investigations conducted by the authors have attested that even a large-volume ...
Motion estimation applied to reconstruct undersampled dynamic MRI
(2007)
Magnetic Resonance Imaging (MRI) has become an important tool for dynamic clinical studies. Regrettably, the long acquisition time is still a challenge in dynamic MRI. Several undersampled reconstruction techniques have ...
