Medical Image Retrieval Based on Hilbert-Huang Transform;

Hilbert-Huang transform spectrum and its application in seismic signal analysis;

Time-frequency spectral analysis of seismic data based on Hilbert-Huang transform

The proposed HVD method was based on the Hilbert transform(HT),just as Hilbert-Huang transform(HHT),but did not involve complicated empirical mode decomposition(EMD).

The Hilbert-Huang transform(HHT) is a new method of time-frequency spectrum treatment that calls for the decomposition of time sequenced data by empirical modes(EMD) which is followed by a Hilbert transform (HT).

The Hilbert-Huang Transformation (HHT) consists of the following steps: First, decomposition of time sequenced data by empirical modes (EMD) followed by a Hilbert transformation to obtain a new method of spectrum treatment.

To deal with the problem of ineffective extraction in underwater target feature extraction methods based on traditional time-frequency analysis,a new time-frequency analysis method,the Hilbert-Huang Transform(HHT) was applied.
