Directional EMD and its application to texture segmentation
Z Liu, S Peng - Science in China Series F: Information Sciences, 2005 - Springer
In this paper we present the definition and framework of Directional Empirical Mode
Decomposition (DEMD) and use DEMD to do texture segmentation. As a new technique of
time-frequency analysis, EMD decomposes signals by sifting and then analyzes the
instantaneous frequency of the obtained components called Intrinsic Mode Functions (IMFs).
Compared with Bidimensional EMD (BEMD) which only extracts textures by radial basis
function interpolation, the virtues of DEMD include: the directional quality is considered in …
