Signal denoising optimization based on a Hilbert-Huang transform-triple adaptable wavelet packet transform algorithm [PDF]
, 2019 The Hilbert-Huang transform (HHT) can retain intrinsic signal characteristics after noise reduction but still leaves a slightly noisy signal, and the wavelet packet transform (WPT) denoising algorithm eliminates noise efficiently but causes distortion of

Hilbert-Huang Transform-based Local Regions Descriptors [PDF]
Procedings of the British Machine Vision Conference 2007, 2007 This paper presents a new interest local regions descriptors method based on Hilbert-Huang Transform. The neighborhood of the interest local region is decomposed adaptively into oscillatory components called intrinsic mode functions (IMFs). Then the Hilbert transform is applied to each component and get the phase and amplitude information. The proposed

Estimates of Extreme and Low Frequency Reef‐Flat Water Levels at Ipan, Guam From Offshore Waves
Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.Abstract Wave and water level observations collected at a shore‐attached fringing reef at Ipan, Guam are used to relate offshore wave conditions and reef water levels to extreme water levels near the shoreline (2% $\%$ exceedance, η2 ${\eta }_{2}$). The observations capture conditions during three extreme storm events, including Typhoon Dolphin that ...

European Journal of Neuroscience, Volume 64, Issue 2, July 2026.Neuromodulation therapies for pain, such as high‐frequency spinal cord stimulation (hSCS), are widely used, yet their effects on TNS‐evoked cortical network dynamics remain unclear. This study demonstrates that hSCS selectively modulates TNS‐evoked cortical cross‐frequency interactions, altering theta‐gamma coupling in a region‐ and time‐dependent ...

Operation of the Hilbert-Huang Transform: basic overview with examples [PDF]
, 2013 This learning object provides a simple explanation of the operation of the Hilbert-Huang transform. This is a tool which has been employed with success in the signal processing field and, more especifically, in the analysis of non-stationary signals. The

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Fractured rocks play a crucial role in myriad natural and engineered systems, including Earth's critical zone, oil/gas/geothermal reservoirs, and geological CO2/H2/waste storage systems. While complex electrical conductivity is extensively used to estimate the pore and grain sizes of conventional porous rocks and soils, it is rarely used to ...
