Image registration is an important technique in image processing, which could be used to compare the similarity between two images. Here, a novel method based on transition probability matrix of oligonucleotide is proposed to infer the evolutionary relatedness of microbial organisms via image registration. Firstly, the oligonucleotide transition probability matrixes of microbial genomes are calculated by applying 1st order Markov Chain Method. Secondly, each transition probability matrix is converted into a color image, and then combined with each other to a joint histogram. Finally, the point set distribution of joint histogram is analyzed, and divergence formula is introduced and used as the similarity metric, which can reflect the evolutionary relatedness of organisms. For the organisms that taxonomic categories covered from kingdom to species, our results suggest that this new method is more accurate and discriminable than the methods based on single gene or oligonucleotide frequency especially for the classification under species. This method must be broadened and developed so that it can be applied to species identification and phylogeny inferring.
