Abstract. In this paper, we investigate the issue of the retrievals of remote sensing images with different spatial resolutions by using texture features. Since the texture features extracted on images with different resolutions are not directly comaprable, we use the resolution or scale invariance of the texture features to make them comparable. Image retrieval experiments are carried out on the database composed by SPOT images at two different resolutions.
