    • Abstract:  Abstract This paper proposes a new rotation-invariant and scale-invariant representation for texture image retrieval based on steerable pyramid decomposition. By calculating the mean and standard deviation of decomposed image subbands, the texture feature vectors are extracted. To obtain rotation or scale invariance, the feature elements are aligned by considering either the dominant orientation or dominant scale of the input textures. Experiments were conducted on the Brodatz database aiming to compare our approach to the conventional steerable pyramid decomposition, and a proposal for texture characterization based on Gabor wavelets with regard to their retrieval effectiveness. Results demonstrate the superiority of the proposed method in rotated and scaled image datasets.

            A PERSON WHO skirts through the sports section with only a quick glimpse of the headlines might come to think of baseball season as little more than a 6-month series of strains, sprains and broken bones. To chronicle a team is to become well-versed in all of the above, as Phillies fans have no doubt realized given lengthy stays on the disabled list by stars like Jimmy Rollins, Chase Utley, and ...

            The rotation of the planet Venus is slowing down, according to recent data gathered by the European Space Agency's Venus Express satellite. Peering through the planet's dense atmosphere with infrared imaging, the orbiter saw surface features up to 20 km (12.4 miles) from their expected location. The discrepancy could be explained if the Venusian day has lengthened by six and a half minutes since ...
