| Abstract | Because of the diversity of the textures, pre-classification before the retrieval seems very necessary and important. We divided texture images into two categories: structure and random, based on binary Fourier spectrum and Shannon entropy as a pre-classification stage. Gabor wavelets is especially useful for texture analysis because of the tunable property of its scale and orientation, but it is sensitive to the directional change of a query image. Scale-invariance Gabor representation is used here after the adjustment step which can reduce the rotation variance of the query image to achieve rotation-invariance, scale-invariance and translation-invariance task in the first class. For the images in the latter class we use a combined rotation and scale invariant Gabor representation. The features we used are much less than conventional Gabor wavelets and therefore it is less time-consuming not only in feature extraction but also in similarity measurement. Simulation results using Brodatz database clearly show that our proposed rotation-invariant, scale-invariant and translation-invariant methods give rise to high retrieval performances. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
