DISTINCTION OF TWO DIFFERENT NON-STATIONARY SIGNALS WITH HILBERT-HUANG TRANSFORM [PDF]

, 2020
: In order to distinguish the difference of non-stationary signals, the novel time-frequency analysis approach, i.e. Hilbert-Huang transform (HHT), is applied in this paper. Firstly, Hilbert-Huang transform is briefly introduced.

Steganalysis of Enhanced BPCS Steganography Using the Hilbert-Huang Transform Based Sequential Analysis [PDF]

, 2008
In this paper, we present a steganalytic method to attack the enhanced BPCS steganography (for short EBPCS) proposed by Niimi et al. The key element of the method is analysis of the bitplane-block complexity difference sequences between stego images and ...

HILBERT-HUANG TRANSFORM ANALYSIS OF SOUND OF VERTICAL BAMBOO FLUTE (DONGXIAO) [PDF]

, 2007
This study applies the Hilbert-Huang Transform (HHT) as a tool for dongxiao timbre analysis, and compares the results with those of Short-Time Fourier Transform. Because the donxiao timbre is not very stationary (especially at the beginning of the timbre)
