Abstract

Aimed at the problems of hyperspectral images unmixing, it is found that the unmixing accuracy of the traditional unmixing algorithm is not high when the number of endmember keeps constant in unmixing. Thus, based on the ANN, this paper proposed a novel unmixing algorithm of estimating the number and category of endmember in a single pixel. Firstly, the unmixing algorithm used the ANN to estimate the number and category of each mixed pixel's endmember in the remote sensing image. Then, it determined the objective function of the algorithm based on the estimation results, and introduced the improved differential search algorithm to solve the objective function. Finally, it obtained the abundances and the parameters to realize the unmixing of hyperspectral images. The experimental results on simulated and real hyperspectral data demonstrate that compared with the existing unmixing algorithms, the proposed unmixing algorithm has higher performance and is more in line with the actual scene.
