Embodiment Construction
[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0063] The object of the present invention is to provide a mixed pixel unmixing method and system for a linear model of a space man-made target. In the non-negative matrix decomposition, a quadratic function constraint term representing the sparsity of material abundance and a space group sparsity constraint term are introduced to improve The accuracy of mixed pixel unmixing is improved.
[0064] In order to make the above objects, features and advantages of t...
