Similarity analysis of DNA sequences based on the EMD method
2011
Abstract DNA sequences can be translated into 2D graphs and into numerical sequences; we call the numerical sequences nonlinear signal sequences. We can use the empirical mode decomposition (EMD) method to divide nonlinear signal sequences into a group of well-behaved intrinsic mode functions (IMFs) and a residue, so that we can compare the similarities among DNA sequences conveniently and intuitively. This work tests the method’s suitability by using the mitochondria of four different species.
