The classification of remote sensing images is one of the most important issues in remote sensing today. This paper presents a novel classification algorithm for multispectral remote sensing images based on the quantum-behaved particle swarm optimization(QPSO) algorithm and diversity-mutation. To classify remote sensing images, we adopted unsupervised classification, and used the Gaussian distance function between the image pixels and the cluster centers as the classification standard. We used the QPSO algorithm to optimize the cluster centers. For clustering, we propose diversity-mutation to prevent premature convergence of the QPSO algorithm to optimize the classification results. The experimental results show that the proposed algorithm not only has better search speed, but also has higher convergence precision, and searches and optimizes the best cluster center more efficiently. Therefore, we conclude that the algorithm is effective and feasible.
