Two Stage Kalman Estimators with Probabilistically Weighted Average [PDF]

open access: yesEngineering and Technology Journal, 2009
With spherical coordinate, the adaptive estimation using multiple model filtering isenhanced in this paper. The enhancement is achieved by using just two depended parallelKalman filters, instead of multiple models, with the probabilistically weighted ...

A Zero-Velocity Update Method for Adaptive Particle Filtering

open access: yesXibei Gongye Daxue Xuebao, 2020
Aiming at the low precision of Kalman filter in dealing with non-linear and non-Gaussian models and the serious particle degradation in standard particle filter, a zero-velocity correction algorithm of adaptive particle filter is proposed in this paper ...

Modified Proportionate Affine Projection Algorithm Based Adaptive DSTATCOM Control With Increased Convergence Speed

open access: yesIEEE Access, 2022
The three-phase DSTATCOM is prone to higher dynamics due to grid disturbances. The proportionate affine projection algorithm (PAPA) is an adaptive filter that can be used for DSTATCOM control.

Adaptive Kernel Kalman Filter [PDF]

open access: yesIEEE Transactions on Signal Processing, 2021
Sequential Bayesian filters in non-linear dynamic systems require the recursive estimation of the predictive and posterior distributions. This paper introduces a Bayesian filter called the adaptive kernel Kalman filter (AKKF). With this filter, the arbitrary predictive and posterior distributions of hidden states are approximated using the empirical ...

Medical image enhancement using threshold decomposition driven adaptive morphological filter [PDF]

open access: yes, 2008
One of the most common degradations in medical images is their poor contrast quality. This suggests the use of contrast enhancement methods as an attempt to modify the intensity distribution of the image.

On Implementation and Design of Filter Banks for Subband Adaptive Systems

open access: yes, 1998
This paper introduces a polyphase implementation and design of an oversampled K-channel generalized DFT (GDFT) filter bank, which can be employed for subband adaptive filtering, and therefore is required to have a low aliasing level in the subband ...

Recursive Optimal Finite Impulse Response Filter and Its Application to Adaptive Estimation

open access: yesApplied Sciences, 2022
In this paper, the recursive form of an optimal finite impulse response filter is proposed for discrete time-varying state-space models. The recursive form of the finite impulse response filter is derived by employing finite horizon Kalman filtering with

Efficient Subband Adaptive Filtering with Oversampled GDFT Filter Banks

open access: yes, 1997
This paper addresses the numerical efficiency of adaptive filtering implemented in subbands. Our approach first focuses on oversampled GDFT filter banks and their potential benefits over other possible subband decompositions.

Adaptive equalisation in oversampled subbands [PDF]

open access: yes, 1998
The potential presence of fractional delays, non-minimum phase parts, and a colouring of the channel output can require adaptive equalizers to adapt very long filters, which can have slow convergence for LMS-type adaptive algorithms.

Adaptive Kuwahara filter [PDF]

open access: yesSignal, Image and Video Processing, 2015
A new filter was created by improving the standard Kuwahara filter. It allows more efficient noise reduction without blurring the edges and image preparation for segmentation and further analyses operations. One of the biggest and most common restrictions encountered in filter algorithms is the need for a declarative definition of the filter window ...
