Robust train motion model calibration based on M-estimation [PDF]

open access: yes, 2023
Train motion model calibration is crucial to ensure the accuracy and performance of any railway algorithm that requires reproducing and predicting train dynamics. The calibration must be robust against measurement outliers and missing data. However, such

Pan-Sharpening Based on Panchromatic Colorization Using WorldView-2

open access: yesIEEE Access, 2021
In order to overcome the lack of the multispectral image (MS) and adequately preserve the spatial information of panchromatic (PAN) image and the spectral information of MS image, this study proposes a method which adds the spectral information of the ...

Pan-Sharpening Based on Convolutional Neural Network by Using the Loss Function With No-Reference

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
In order to preserve the spatial and spectral information of the original panchromatic and multispectral images, this article designs a loss function suitable for pan-sharpening and a four-layer convolutional neural network that could adequately extract ...

A Class of Estimators for Estimating the Variance of the Ratio Estimator

open access: yesJOURNAL OF THE JAPAN STATISTICAL SOCIETY, 2004
Summary: We have proposed a class of estimators for the variance of the ratio estimator which includes two standard estimators \(V_0\), \(V_2\) and the estimators \(V_H\) and \(V_3\) suggested by \textit{R. M. Royall} and \textit{K. R. Eberhardt} [Sankya, Ser. C 37, 43--52 (1975; Zbl 0335.62007)] and \textit{C. F.

Low-resolution human pose estimation [PDF]

open access: yes, 2022
Human pose estimation has achieved significant progress on images with high imaging resolution. However, low-resolution imagery data bring nontrivial challenges which are still under-studied. To fill this gap, we start with investigating existing methods
