A method, processing system and computer program product for image retrieval. In one aspect, the method includes, in a processing system: determining a query feature set for a search image, wherein the query feature set includes texture data indicative of a texture of the search image for a plurality of resolutions of the search image; determining a dissimilarity measurement between at least one query feature of the query feature set and at least one target feature of a target image set for one or more target images, wherein the dissimilarity measurement is determined at least partially based upon the dissimilarity between the texture data of the search image and one or more target images for at least some of the plurality of resolutions of the target image; and identifying one or more target images based upon the dissimilarity measurement.
