Boosted adaptive filters [PDF]

open access: yesDigital Signal Processing, 2018
Abstract We introduce the boosting notion of machine learning to the adaptive signal processing literature. In our framework, we have several adaptive filtering algorithms, i.e., the weak learners, that run in parallel on a common task such as equalization, classification, regression or filtering.

Mesh Denoising via Adaptive Consistent Neighborhood

open access: yesSensors, 2021
In this paper, we propose a novel guided normal filtering followed by vertex updating for mesh denoising. We introduce a two-stage scheme to construct adaptive consistent neighborhoods for guided normal filtering.

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.

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.

Blind-noise image denoising with block-matching domain transformation filtering and improved guided filtering

open access: yesScientific Reports, 2022
The adaptive block size processing method in different image areas makes block-matching and 3D-filtering (BM3D) have a very good image denoising effect. Based on these observation, in this paper, we improve BM3D in three aspects: adaptive noise variance ...
