Endmember Extraction from Hyperspectral Images Based on Genetic Algorithm and Volume Maximization
Aiming at the problems of low extraction accuracy and high computational complexity in the current volume maximization endmember extraction technology,the Extraction Method Based on Genetic Algorithm and Volume Maximization (EE-GAVM) is proposed to improve the existing endmember extraction methods. The EE-GAVM method locates the endmember set by searching for the pixel vector set with the largest volume of the simplex,and expresses the endmember extraction problem as a single target,which saves computing resources and improves accuracy. The experimental results show that the proposed method outperforms other comparative algorithms in terms of performance and accuracy.
