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.

Compensating for motion estimation inaccuracies in DVC [PDF]

open access: yes, 2010
Distributed video coding is a relatively new video coding approach, where compression is achieved by performing motion estimation at the decoder. Current techniques for decoder-side motion estimation make use of assumptions such as linear motion between ...

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.

Robust motion estimation using connected operators [PDF]

open access: yes, 1997
This paper discusses the use of connected operators for robust motion estimation The proposed strategy involves a motion estimation step extracting the dominant motion and a ltering step relying on connected operators that remove objects that do not fol

Combined wavelet domain and motion compensated filtering compliant with video codecs [PDF]

open access: yes, 2007
In this paper, we introduce the idea of using motion estimation resources from a video codec for video denoising. This is not straightforward because the motion estimators aimed for video compression and coding, tolerate errors in the estimated motion ...

Adaptive Multi-Pattern Fast Block-Matching Algorithm Based on Motion Classification Techniques [PDF]

open access: yes, 2007
Motion estimation is the most time-consuming subsystem in a video codec. Thus, more efficient methods of motion estimation should be investigated. Real video sequences usually exhibit a wide-range of motion content as well as different degrees of detail,

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.
