| Abstract | Understanding the spatio-temporal gene expression patterns is critical in studying genes roles and their complicated relationships. With the availability of high-resolution digital images of in situ mRNA hybridization expression pattern of Drosophila embryos collected through both the Berkeley Drosophila Transcriptional Network Project (BDTNP) and the Berkeley Drosophila Genome Project (BDGP), we will be able to answer a series of interesting questions, e.g., what are the variations of gene expression patterns, what are the patterning process of gene expression, etc. To achieve these goals at a large scale, it is extremely important to automate the image mining and informatics processes of embryogenesis expression patterns. We developed computer programs to register, compare and analyze these spatio-temporal pattern images. In this talk, I will review four projects on image mining of fruitfly embryo gene expression patterns: (a) Gaussian mixture model based embryonic expression pattern extraction and comparison, (b) Gene expression pattern clustering using novel MSTCUT and probabilistic ensemble clustering techniques, (c) Surface/volume models for 3D modeling and registration of early embryos, and (d) A manifold learning method for spatio-temporal registration of 3D gene expression patterns and reconstruction of the embryonic developmental time series. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
