    With the development of the remote-sensing imaging technology, there are more and more applications of hyperspectral image
    classification tasks, in which to select a minimal and effective subset from a mass of bands is the key issue. This paper
    put forward a novel band selection strategy based on conditional mutual information between adjacent bands and branch and
    bound algorithm for the high correlation between the bands. In addition, genetic algorithm and support vector machine are
    employed to search for the best band combination. Experimental results on two benchmark data set have shown that this approach
    is competitive and robust.
