...In this paper, it is proposed to use EMD to obtain the IMFs of hyperspectral image bands and to use these IMFs in the classification step to provide increased classification accuracy....

...It is seen that the lower order IMFs such as the first and second IMFs are much more structured and reflect the spatial structural content of the image and that higher order IMFs have a rather low-pass characteristic and lack local spatial structure....

...In order to obtain meaningful instantaneous frequency, restrictive conditions have to be imposed on the data as discussed by Gabor (1946), Bedrosian (1963) and, more recently, Boashash (1992): for any function to have a meaningful instantaneous frequency, the real part of its Fourier transform has…...

...Therefore, the parameter, ν, defined as N21 −N20 = 1 π2 m4m0 −m22 m2m0 = 1 π2 ν2, (3.7) offers a standard bandwidth measure (see, for example, Rice 1944a, b, 1945a, b; Longuet-Higgins 1957)....
