| Abstract: | In this paper,basic principle of MAP method was introduced,observation models that were appropriate for hyperspectral images were constructed,and a cost function of the model was given.Assuming that hyperspectral image pixels were independent,a solution method for the cost function was given,and then,the MAP based hyperspectral image enhancement process was analyzed.A PHI hyperspectral image dataset and its corresponding high resolution panchromatic image were used to conduct the MAP based hyperspectral ima... |
