Motion Compensation on DCT Domain [PDF]
EURASIP Journal on Advances in Signal Processing, 2001 Alternative fully DCT-based video codec architectures have been proposed in the past to address the shortcomings of the conventional hybrid motion compensated DCT video codec structures traditionally chosen as the basis of implementation of standard ...

Motion compensated projection reconstruction [PDF]
Magnetic Resonance in Medicine, 1999 Over recent years, MRI has shown the capability for real-time applications. Although the acquisition times of fast MRI methods have been reduced significantly, patient motion during a magnetic resonance imaging (MRI) examination still causes artifacts in the image.

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.

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.

Event-Based Motion Segmentation by Motion Compensation [PDF]
, 2019 In contrast to traditional cameras, whose pixels have a common exposure time, event-based cameras are novel bio-inspired sensors whose pixels work independently and asynchronously output intensity changes (called "events"), with microsecond resolution ...

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 ...
