Motion Error Estimation and Compensation of Airborne Array Flexible SAR Based on Multi-Channel Interferometric Phase

Remote Sensing, 2023
Airborne array synthetic aperture radar (SAR) has made a significant breakthrough in the three-dimensional resolution of traditional SAR. In the airborne array SAR 3D imaging technology, the baseline length is the main factor restricting the resolution ...

Progressive mesh-based motion estimation using partial refinement [PDF]

, 2006
A technique for performing progressive mesh-based motion estimation in a layered fashion is presented. Motion compensation based on image warping provides a block prediction free of block artifacts.

Motion compensation using joint-sub-band phase unwrapping for synthetic aperture sonar [PDF]

JASA Express Letters, 2022
Displaced phase center antenna (DPCA) micro-navigation has been widely applied in the motion compensation of synthetic aperture sonars (SASs). Estimating the time delay is the most important step for DPCA-based motion compensation.

Slice group based multiple description video coding with three motion compensation loops [PDF]

, 2005
The paper proposes a novel scheme for a multiple description video coding approach using the slice group coding tool proposed in H.264. Three motion compensation loops, one central and two side loops, are maintained for two descriptions in the encoder ...

Motion compensation with a scanned ion beam: a technical feasibility study

Radiation Oncology, 2008
Background Intrafractional motion results in local over- and under-dosage in particle therapy with a scanned beam. Scanned beam delivery offers the possibility to compensate target motion by tracking with the treatment beam.

Motion Parameter Identification and Motion Compensation for Shipborne HFSWR by Using the Reference RF Signal Generated at the Shore

Remote Sensing, 2020
The shipborne high-frequency surface wave radar (HFSWR) platform produces six degrees of freedom (DOF) motion at sea, which affects the performance of radar target detection and remote sensing of ocean surface dynamics parameters. Motion compensation can

Motion compensated de-interlacing with adaptive global motion estimation and compensation [PDF]

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
A motion compensated de-interlacing method with adaptive global motion estimation and compensation is proposed to recover the defects of interlaced video sequence with camera panning, rotating or zooming. GME and GMC are used to recover the change of the whole picture due to camera motions.

Error concealment using motion field interpolation [PDF]

, 1998
In the context of block-based video coding, two error concealment algorithms are presented. The first algorithm is based on bilinear motion field interpolation (BMFI). For each pel in a damaged block, the algorithm recovers a motion vector using bilinear
