| Abstract | Operation video recording is one of efficient methods for analyzing surgical workflow and intraoperative incident detection. In “Intelligent Operating Room” at Tokyo Women's Medical University Hospital, the special neurological surgery called awake craniotomy is recorded by video recording system IEMAS (Intraoperative Examination Monitor for Awake Surgery). There are a number of useful video records of surgical procedure such as patient reactions and surgical operations. However, these surgical event tags which are used for surgcial workflow analysis are not contained in IEMAS records. IEMAS is composed multi-view video cameras, so manual tagging for video records is a lot of labor because of the large length of surgical operation videos. In awake craniotomy, electrical stimulation is one of significant surgical operations for detecting eloquent brain areas. In this paper, we propose the automatic detection method for the stimulation points onto patient's brain areas from raw IEMAS video records by using image processing approach. In the previous work, we proposed stimulation timing detection method from surgery sound records of IEMAS. Hence, we propose a detection method of surgical instrument for electrical stimulation in order to tag the stimulated positions on surgical view. However, detected positions on the video frame coordinates depend on camera view changes. Therefore, we map video frame positions to representative video frame positions by using homography transformation in order to enable to analyze stimulated points relation. We applied automatic video tagging method for several raw IEMAS video records and show its performance. |

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.
