Compressive Video Recovery Using Block Match Multi-Frame Motion Estimation Based on Single Pixel Cameras

open access: yesSensors, 2016
Compressive sensing (CS) theory has opened up new paths for the development of signal processing applications. Based on this theory, a novel single pixel camera architecture has been introduced to overcome the current limitations and challenges of ...

Backward adaptive pixel-based fast predictive motion estimation [PDF]

open access: yes, 2009
This letter presents a novel backward adaptive pixel-based fast predictive motion estimation (BAPME) scheme for lossless video compression. Unlike the widely used block-matching motion estimation techniques, this method predicts the motion on a pixel-by ...

A Novel Parallel Motion Estimation Design and Implementation on GPU

open access: yesIEEE Access, 2019
The development of high-resolution video mounts a serious challenge to the previous video coding standard. The appearance of the new generation standards greatly relieves the dilemma but increases the coding complexity dramatically.

Evolutionary strategy based improved motion estimation technique for H.264 video coding [PDF]

open access: yes, 2006
In this paper we propose an improved motion estimation algorithm based on evolutionary strategy (ES) for H.264 video codec applied to video. The proposed technique works in a parallel local search for macroblocks.

Deep learning-based image reconstruction and motion estimation from undersampled radial k-space for real-time MRI-guided radiotherapy

open access: yesPhysics in Medicine and Biology, 2020
To enable magnetic resonance imaging (MRI)-guided radiotherapy with real-time adaptation, motion must be quickly estimated with low latency. The motion estimate is used to adapt the radiation beam to the current anatomy, yielding a more conformal dose ...

Bayesian Estimation of Turbulent Motion [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2013
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 property between histograms of motion increments computed at different scales.
