| Abstract | Most Driver Status Monitoring (DSM) systems consist of spatial features extractions and temporal status recognition in sequence. Extracting the spatial features, which include driver facial behavior such as eye closing and mouth opening, generally requires considerable computation. It causes DSM systems to lose the valuable instantly-occurring driver facial information during real-time processing. Loss of facial information affects the accuracy of the system, and its impact is more severe on restricted computing resources. To solve this problem, this paper proposes an Adaptive Batch-Image (ABI) based DSM (ABI-DSM) system. The ABI enables the DSM system to use images captured in real-time while the DSM process previous input images. For real-time operation on a lightweight GPU-equipped Single-Board Computer (SBC), the ABI-DSM system is designed as follows. First, the system uses the driver's facial behavior to reduce the dimension of the time-series data for recognizing the status of the driver. The second, detection and tracking of driver's faces are not used for facial behavior recognition. Also, the system works with PydMobileNet, which has lower parameters and FLOPs than MobileNetV2, for facial behavior recognition. Experiments show that the ABI-DSM systems based on MobileNetV2 and PydMobileNet perform better than others in terms of both FPS and Precision. In particular, the PydMobileNet-based ABI-DSM system outperforms competitors when the size of Batch-Image is over six images. |

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.
