An Algorithm for Improving Hilbert-Huang Transform [PDF]
, 2007 The Hilbert-Huang transform is viewed as a promising method to process the nonlinear and non-stationary signal. However, it hasn't been a general method in signal processing due to its some deficiencies. In this paper, an algorithm is proposed to resolve one of its deficiencies that the EMD will generate redundant IMFs at the low-frequency region. This

IRIS RECOGNITION BASED ON HILBERT–HUANG TRANSFORM
Advances in Adaptive Data Analysis, 2009 As a reliable approach for human identification, iris recognition has received increasing attention in recent years. This paper proposes a new analysis method for iris recognition based on Hilbert–Huang transform (HHT). We first divide a normalized iris image into several subregions.

An Application to Transient Current Signal based Induction Motor Fault Diagnosis of Fourier-Bessel Expansion and Simplified Fuzzy ARTMAP [PDF]
, 2013 The start-up transient signals have been widely used for fault diagnosis of induction motor because they can reveal early defects in the development process, which are not easily detected with the signals in the steady state operation. However, transient
