On optimal smoothing and derivative estimation from noisy displacement data in biomechanics

HJ Woltring - Human Movement Science, 1985 - Elsevier
Estimating derivatives from noisy displacement data is a notoriously ill-posed problem in
signal processing and biomechanics. Following the work of Wood and Jennings (1978) and …

Extrapolation and spectral estimation with iterative weighted norm modification

SD Cabrera, TW Parks - IEEE Transactions on Signal …, 1991 - ieeexplore.ieee.org
An algorithm is developed to define, from the data samples themselves, a frequency-
weighted norm to use in minimum-weighted-norm extrapolation. The iterative procedure …

Interpolation and the discrete Papoulis-Gerchberg algorithm

PJSG Ferreira - IEEE Transactions on Signal Processing, 1994 - ieeexplore.ieee.org
Analyze the performance of an iterative algorithm, similar to the discrete Papoulis-Gerchberg

Iterative and noniterative recovery of missing samples for 1-D band-limited signals

PJSG Ferreira - Nonuniform Sampling: Theory and Practice, 2001 - Springer
This chapter discusses a class of iterative and noniterative methods for the reconstruction of
partially known band-limited signals. Band-limiting is equivalent to the vanishing of a known …

On the use of singular value decomposition and decimation in discrete-time band-limited signal extrapolation

B Sullivan, B Liu - IEEE Transactions on Acoustics, Speech …, 1984 - ieeexplore.ieee.org
The problem of extrapolating a band-limited signal in discrete time is viewed as one of
solving an underdetermined system of linear equations. Choosing the minimum norm least …

Noniterative and fast iterative methods for interpolation and extrapolation

PJSG Ferreira - IEEE Transactions on Signal Processing, 1994 - ieeexplore.ieee.org
In this correspondence we study the band-limited interpolation and extrapolation problems
for finite-dimensional signals. We show that these problems can be easily reduced to the …

Unified Hilbert space approach to iterative least-squares linear signal restoration

JLC Sanz, TS Huang - JOSA, 1983 - opg.optica.org
We deal with iterative least-squares solutions of the linear signal-restoration problem g= Af.
First, several existing techniques for solving this problem with different underlying models …

Information recovery in missing angular data cases: an approach by the convex projections method in three dimensions

JM Carazo, JL Carrascosa - Journal of Microscopy, 1987 - Wiley Online Library
We have studied the method of projections on to convex sets (POCS) for the restoration of
three‐dimensional signals, especially applied for the degraded information obtained in three …

Reconstruction of source distributions from sound pressures measured over discontinuous regions: Multipatch holography and interpolation

M Lee, JS Bolton - The Journal of the Acoustical Society of America, 2007 - pubs.aip.org
In the present work, a method of alternating orthogonal projections is described in the
context of near-field acoustical holography; it allows missing (or “not measured”) data to be …
