Journal ArticleDOI
Noise reduction and data recovery for a VLF-EM survey using a nonlinear decomposition method
TL;DR: In this paper, the authors used a nonlinear decomposition technique called the empirical mode decomposition EMD method with the Hilbert transform to obtain more reliable low frequency electromagneticVLF-EM data.
Journal ArticleDOI
Adaptive filtering of random noise in near-surface seismic and ground-penetrating radar data
TL;DR: In this paper, two adaptive algorithms, the optimum 2D median filter and the 2D adaptive Wiener filter, were designed by adopting adaptive algorithms to suppress speckle noise in 2D digital image data.
Journal ArticleDOI
Subsurface GPR imaging of a potential collapse area in urban environments
Yih Jeng,Chih Sung Chen +1 more
TL;DR: In this paper, a ground penetrating radar survey in a potential collapse urban area was performed, where the acquired data were processed through the logarithmic transformed ensemble empirical mode decomposition (EEMD) methodology that reduces the exponential decay of the original data and extracts meaningful images.
Journal ArticleDOI
Nonlinear data processing method for the signal enhancement of GPR data
Chih Sung Chen,Yih Jeng +1 more
TL;DR: An alternative data processing procedure is proposed for enhancing the signal/noise (S/N) ratio of ground penetrating radar (GPR) data by performing the logarithmic transform in conjunction with the ensemble empirical mode decomposition (EEMD), a new nonlinear data analysis method in signal processing.
Journal ArticleDOI
Application of sub-image multiresolution analysis of Ground-penetrating radar data in a study of shallow structures
TL;DR: A comparison of results from this method and from conventional filtering techniques demonstrates the effectiveness of the sub-image MRA method, particularly in removing ringing noise and scattering events, as shown in the field study.
