| Abstract | Recently, efficiently representing the scenes from a large volume of high spatial resolution (HSR) images is a critical problem to be solved. Traditional scene classification problems were solved by utilizing the spatial, spectral and structural features of the HSR images separately or jointly, which lacks considering all those features of the images integrally and automatically. In this paper, we propose an efficient hierarchical convolutional sparse auto-encoder (HCSAE) algorithm considering all the features of the images integrally for scene classification, which adopts the unsupervised hierarchical idea based on the single-hierarchy convolutional sparse auto-encoder (CSAE). Compared with the single-hierarchy CSAE, HCSAE can extract more robust and efficient features containing abundant detail and structural information in the higher hierarchy for scene classification. To further improve the calculation performance and reduce the over-fitting of the network, a “dropout” strategy is adopted in this paper. The experimental results were confirmed by the UC Merced dataset consisting of 21 land-use categories, and showed that HCSAE performs better than the traditional scene classification methods and the single-hierarchy CSAE algorithm. |

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.
