Adaptive acoustooptic filter [PDF]

open access: yesApplied Optics, 1984
A new adaptive filter utilizing acoustooptic devices in a space integrating architecture is described. Two configurations are presented; one of them, suitable for signal estimation, is shown to approximate the Wiener filter, while the other, suitable for detection, is shown to approximate the matched filter.

Large-scale wave-front reconstruction for adaptive optics systems by use of a recursive filtering algorithm [PDF]

open access: yes, 2005
We propose a new recursive filtering algorithm for wave-front reconstruction in a large-scale adaptive optics system. An embedding step is used in this recursive filtering algorithm to permit fast methods to be used for wave-front reconstruction on an ...

Adaptive Kalman Filtering

open access: yesJournal of Research of the National Bureau of Standards, 1985
The increased power of small computers makes the use of parameter estimation methods attractive. Such methods have a number of uses in analytical chemistry. When valid models are available, many methods work well, but when models used in the estimation are in error, most methods fail.

Improved Non-local Means Filtering Algorithm [PDF]

open access: yesJisuanji gongcheng, 2016
The non-local means filtering algorithm is an efficient denoising algorithm that can restore details of image texture well.However,the algorithm cannot adaptive adjust filtering parameters and the filtering result is easy to produce artifacts.Owing to ...

Adaptive clutter reduction based on wavelet transform and principal component analysis for ground penetrating radar

open access: yesLeida xuebao, 2015
Because of the limitations of traditional Principal Component Analysis (PCA) in clutter reduction, an improved PCA subspace method is proposed based on the 2D wavelet transform.
