Enhancing Image Quality via Robust Noise Filtering Using Redescending M-Estimators [PDF]

open access: yesEntropy, 2023
In the field of image processing, noise represents an unwanted component that can occur during signal acquisition, transmission, and storage. In this paper, we introduce an efficient method that incorporates redescending M-estimators within the framework

A Geometric Estimation Technique Based on Adaptive M-Estimators: Algorithm and Applications

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Robust fitting is a basic technique and has been widely applied in photogrammetry and remote sensing, such as geometric correction. As known, typical robust estimators (include M-estimators, S-estimators, MM-estimators, etc.) often fail when outlier rate

Generalized Shrunken-Type M Estimation [PDF]

open access: yesThe Egyptian Statistical Journal, 2003
It is important in regression analysis to detect the leverage data points that exert an unduly large effect on the least squares estimation. However, in practical situations, the existence of leverage data points is complicated by the presence of ...

Estimators of Bolometric Luminosity and Black Hole Mass with Mid-infrared Continuum Luminosities for Dust-obscured Quasars: Prevalence of Dust-obscured SDSS Quasars

open access: yesThe Astrophysical Journal, 2023
We present bolometric luminosity ( L _bol ) and black hole (BH) mass ( M _BH ) estimators based on mid-infrared (MIR) continuum luminosity (hereafter, L _MIR ) that are measured from infrared (IR) photometric data.

M-estimators for isotonic regression [PDF]

open access: yesJournal of Statistical Planning and Inference, 2012
In this paper we propose a family of robust estimates for isotonic regression: isotonic M-estimators. We show that their asymptotic distribution is, up to an scalar factor, the same as that of Brunk's classical isotonic estimator. We also derive the influence function and the breakdown point of these estimates.

Highly Robust Complex Covariance Estimators With Applications to Sensor Array Processing

open access: yesIEEE Open Journal of Signal Processing, 2023
Many applications in signal processing require the estimation of mean and covariance matrices of multivariate complex-valued data. Often, the data are non-Gaussian and are corrupted by outliers or impulsive noise.
