| Abstract | The assessment of embryos in vitro is an important tool both in In Vitro Fertilization (IVF) treatment and for research purposes. Traditionally, such assessment has been done manually and demands extensive training and expertise. Interobserver variability limits the use of evaluation, and the manual labor increases the cost of treatment and research. To this end, feature extraction and automatic annotation using computer aided tools would both improve objectivity and save time. Due to the sensitivity of embryos, any evaluation must be performed using non-invasive imaging techniques, which sets a limit for the ability to artificially enhance image contrast, and computer aided assessment of microscopic images under clinical conditions also poses a number of difficulties due to the high level of noise and the unpredictable imaging environment. To overcome this, we propose a framework using a Hough Transform (HT) for the extraction of circular shapes in microscopic embryo images, and also use the algorithm for successful automatic profiling of the pronuclear breakdown (PNB) at syngami and detection of its timing. The best results are achieved when using a HT for embryo outline detection in combination with image variance of the embryo interior. Using our method, we achieve an overall accuracy of 95.0% detecting the position of the embryo outline, and 83.0% detecting the timing of the PNB. |

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.
