Abstract: Using Gabor wavelet texture features, this paper proposes a content-based retrieval algorithm on remote sensing images. A descriptor of sensing image texture feature, in which the scale, direction and structure of texture are combined, is introduced, and guarantees the reliability of distinguishing on texture structure direction. The similarity between query and remote sensing images is computed by using normalized Euclidean distance. The algorithm can be executed faster than others based on Gabor wavelet because of the feature representation and similarity computing. The emulation and application show its effect.
