Abstract: Remote sensing image retrieval (RSIR) aims to find relevant images of a query image from a remote sensing image retrieval dataset. But the similarity between a query image and a retrieval image is generally used and the relationship among images on the retrieval dataset is neglected during the retrieval process. To deal with the problem, this paper presents a new retrieval method based on ant colony optimization (ACO) for RSIR. First, our method uses the pheromone to represent the similarity between images on the retrieval dataset; then the pheromone matrix is updated by ACO. Finally, the pheromone of images is used to improve the performance of RSIR. Meanwhile, an improved weighted image-to-class distance is used to measure the similarity between two images for further improving the retrieval performance. Extensive experiments are conducted on two publicly available remote sensing image databases, UCMD and PatternNet. Compared with the state-of-the-art methods, the proposed method can achieve better retrieval results.
