Embodiment Construction
[0039] A kind of construction method of the mixed pixel unmixing model based on correlation entropy induction measure of the present invention, comprises the following steps successively:
[0040] a) Calculate the number of end members included in the mixed pixel matrix Y according to the virtual dimension method.
[0041] b) Initialize the endmember matrix U and the abundance matrix V. Set the value of q to be greater than 0 and less than 2.
[0042] c) According to the unmixing model based on the sparsity-constrained correlation entropy-induced metric,
[0043]
[0044] Iterate over related variables. in Refers to the mixed pixel matrix including various noises, nonlinearities and abnormal points, Represents the endmember matrix extracted from the mixed pixel matrix Y containing various noises, nonlinearities and outliers, represents the corresponding endmember abundance matrix.
[0045] c1) by U=U*[|(E-Y)V T |-(E-Y)V T ] / (2UVV T ), iteratively calculate the e...
