Adaptive Kernel Kalman Filter [PDF]
IEEE 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 ...

Adaptive Kuwahara filter [PDF]
Signal, 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 ...

Observations on adaptive vector filters for noise reduction in color images
, 2004 In a series of papers, Plataniotis et al. proposed a number of filters for noise reduction in color images where the noise type is unknown. In this letter, those filters with a unified notation are summarized, and it is shown that they are essentially ...

A novel heuristic for the analysis of block sign LMS algorithm
Electronics Letters, 2023 This paper presents a new heuristic for the analysis of adaptive filtering algorithms. It combines Price's Theorem (which is strictly valid when the random variables are jointly Gaussian) with a probabilistic model of the input data that assumes ...

Polyphase Analysis of Subband Adaptive Filters
, 1999 In this paper, we derive a polyphase analysis to determine the optimum filters in a subband adaptive filter (SAF) system. The structure of this optimum solution deviates from the standard SAF approach and presents its best possible solution only as an ...

A high throughput adaptive DFE for HIPERLAN [PDF]
, 1996 This paper describes two methods for increasing the throughput of an adaptive decision feedback equaliser (DFE) using the LMS training algorithm. In the first method, a signed power-of-two number representation is used for the equaliser input data. Using

Adaptive parameters for tracking filters innovation system
Advances in Mechanical Engineering, 2016 One of the most important parts in target tracking is the filter algorithm. In the practical engineering, α-β-γ and α-β-γ-δ filters are often applied due to its simpler arithmetic operations.
