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 ...

FPGA Implementation of Efficient Adaptive Filter Incorporating Systolic Architecture [PDF]

open access: yesEngineering and Technology Journal
This paper introduces an approach that capitalizes on the retimed delay concept to enhance adaptive filters' operational efficiency. In particular, it introduces an adaptive filter configuration with minimal critical path delay.

Adaptive parameters for tracking filters innovation system

open access: yesAdvances 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.

Double‐state chi‐square test based sparse grid quadrature filtering algorithm and its application in integrated navigation

open access: yesIET Control Theory & Applications, 2023
Aiming to reduce the impact that the measurement uncertainty of nonlinear system brings to filtering accuracy, a novel sparse grid quadrature filter (SGQF) algorithm based on the double‐state chi‐square test is proposed.

Comparative study of low-pass filter and phase-locked loop type speed filters for sensorless control of AC drives

open access: yesCES Transactions on Electrical Machines and Systems, 2017
High quality speed information is one of the key issues in machine sensorless drives, which often requires proper filtering of the estimated speed. This paper comparatively studies typical low-pass filters (LPF) and phase-locked loop (PLL) type filters ...

Adaptive Quotient Filters [PDF]

open access: yesProceedings of the ACM on Management of Data
Filters trade off accuracy for space and occasionally return false positive matches with a bounded error. Numerous systems use filters in fast memory to avoid performing expensive I/Os to slow storage. A fundamental limitation in traditional filters is that they do not change their representation upon seeing a false positive match.
