Filtering Methods for Coupled Inverse Problems
SIAM Journal on Applied Dynamical Systems, 2023 We are interested in ensemble methods to solve multi-objective optimization problems. An ensemble Kalman method is proposed to solve a formulation of the nonlinear problem using a weighted function approach. An analysis of the mean field limit of the ensemble method yields an explicit update formula for the weights. Numerical examples show the improved

Design method of nonsubsampled graph filter banks
Dianzi Jishu Yingyong, 2019 In order to overcome the problem that it is difficult to accurately define the downsampling operation for a generalized graph signal in graph filter banks, this paper focuses on the design algorithm of nonsubsampled graph filter banks.

Depth-Based Object Tracking Using a Robust Gaussian Filter
, 2016 We consider the problem of model-based 3D-tracking of objects given dense depth images as input. Two difficulties preclude the application of a standard Gaussian filter to this problem.

Synthesis of multi‐band filters based on multi‐prototype transformation
IET Microwaves, Antennas & Propagation, 2021 In this article, a new synthesis method for generalized multi‐band filters has been proposed. Different from the traditional frequency transformation method, which transforms a low‐pass prototype into a multi‐band filter, multiple low‐pass prototypes ...

Hybrid Filter Based on Fuzzy Techniques for Mixed Noise Reduction in Color Images
Applied Sciences, 2019 To decrease contamination from a mixed combination of impulse and Gaussian noise on color digital images, a novel hybrid filter is proposed. The new technique is composed of two stages.

A design method for multirate filters
ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005 A systematic design method for multirate filters which play an important role in sampling rate conversion techniques is proposed in this paper. Purpose of the proposed approach is directed toward circuit complexity reductions. A circuit complexity evaluating measure including quantization error effects is introduced. A transfer function is divided into

UWB microstrip filter design using a time-domain technique [PDF]
, 2005 A time-domain technique is proposed for ultra-wideband (UWB) microstrip-filter design. The design technique uses the reflection coefficient (S11) specified in the frequency domain. When the frequency response of the UWB filter is given, the response will

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.
