Generic algorithms for motion compensation and transformation
SPIE Proceedings, 2008In this paper, we propose algorithms that map the low-level motion compensation and transformation functions of MPEG-1/2, H.263/MPEG-4 ASP and H.264/MPEG-4 AVC video codecs onto common workflows. This way, a single discrete implementation of luma prediction, chroma prediction and residual transform stages is sufficient for all covered video coding ...

An Aeromagnetic Compensation Algorithm Based on a Deep Autoencoder
IEEE Geoscience and Remote Sensing Letters, 2022Magnetic compensation is a necessary step in the aeromagnetic data processing. While the aeromagnetic compensation model is a linear regression model, the multicollinearity of the variables in the model reduces the accuracy of the compensation model. To solve this problem, we propose a deep autoencoder (DAE) aeromagnetic compensation algorithm. The DAE

Compensation of the RLS algorithm for output nonlinearities
IEEE Transactions on Automatic Control, 1999Summary: It is shown how the recursive least squares (RLS) algorithm can be modified to compensate for a priori known errors of linearity in the output measurement. A novel signal model is used for this purpose. Only the nonlinear effects are modeled by an output error model, and much of the output measurements are used directly in the regression ...

An algorithm for eddy currents symmetrization and compensation
Magnetic Resonance in Medicine, 1996AbstractEddy currents, which are induced in the magnet cryostat by pulsed magnetic field gradients in MRI, generate undesired eddy fields within the imaging volume. In this work, an automated and computerized algorithm to compensate these eddy currents is presented.

In this paper, we propose a novel motion compensation (MC) algorithm. Compared with previous MC algorithm using only one interpolation method, the proposed MC algorithm chooses different interpolation methods according to the calculated sum of absolute difference (SAD) in the process of motion estimation (ME).

An outage compensation algorithm for WLANs
2013 International Conference on Smart Communications in Network Technologies (SaCoNeT), 2013In this paper we propose an algorithm to address the emergency case of an access point (AP) failure by adjusting a radio parameter of the neighboring APs. The goal is to minimize the coverage gap while at the same time: a) restrain imposed interference as much as possible and b) provide adequate load fairness among the APs.

Performance evaluation of the Amplitude Compensation and Dilation Compensation retracking algorithm
2022Altimetric measurements are key for a variety of areas in geoscience, such as studies on ocean weather, surface wave forecasting, or the assessment of climate change and its impacts. SAR mode altimetric records are used to estimate geophysical parameters over water, such as sea level or wave heights, with high resolution and accuracy required by ...

Quality assessment for listening-room compensation algorithms
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010In this contribution various objective measures that can be used to evaluate speech dereverberation algorithms by means of listening-room compensation (LRC) are compared to subjective listening tests. It is shown that technical measures describing the impulse responses are suitable for evaluation of such algorithms. Most signal-based objective measures

Coding algorithm with region-based motion compensation
IEEE Transactions on Circuits and Systems for Video Technology, 1997This paper describes a region-based coding algorithm developed by Thomson Multimedia and submitted to MPEG-4 tests of November 1995 and January 1996. In this algorithm, the segmentation into regions is based on an advanced motion analysis, successively achieving a multiresolution motion field estimation and a segmentation based on a Markovian ...

Tilt-compensating algorithm for phase-shift interferometry
Applied Optics, 2002A self-calibrating algorithm for phase-shift interferometry is described that is able to cancel the effect of accidental relative tilts that may occur during phase stepping. The algorithm is able to retrieve both the phase steps and the tilts that accompany them.
