| Abstract | A supervised segmentation of a 3D seismic section is carried out using wavelet packet transform with the Daubechies-2 orthogonal base and multichannel Gabor filtering. Certain features are computed on the wavelet expansion and on the Gabor-filtered signal, and used by a Mahalanobis classifier to recognize and subsequently segment the seismic section. The Gabor filters of the multichannel scheme were designed by considering the minimal classification error in the recognition of geologically well understood zones, taken as patterns. As a result of the segmentation, zones of different internal stratification are identified in the seismic section. This recognition is based on the comparison of the 3D seismic data with the reference patterns extracted from the representative areas, characterized by different textures. A sandy channel is detected in both cases to a given depth. Applied to these data, the methods distinguish clearly between different layers and efficiently separate zones of different internal stratification. |

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.
