    　View Summary

    <p>We developed a fishery and marine skill learning support system as a self-training teaching material. In this study, we evaluated the usefulness of the proposed system by using text mining and searched for the points to be improved in this system. Using this system, we conducted a survey among the students of a fisheries high school using an evaluation sheet with free-form answering. From the results, we extracted five points, namely "learning method using this system", "video operation and technology confirmation", "promotion of understanding by this system", "skill learning at home", and "fun to learn fisheries skills". Among these five points, "promotion of understanding by this system", in which an understanding of the skill is promoted through explanations of skill and skill videos, was evaluated positively. It was also found that a review is effective in utilizing this system. As a point to be improved, it was found that narration should be provided along with the presentation of the subtitles.</p>

  • Estimation of Body Occlusion Using Deep Learning for Advanced Intelligent Video Surveillance System

    Nagayama Itaru, Iwanaga Tatsuya, Uehara Wakaki, Miyazato Takaya

    IEEJ Transactions on Industry Applications ( The Institute of Electrical Engineers of Japan )  141 ( 2 ) 138 - 146   2021 [ Peer Review Accepted ]

    Type of publication: Research paper (scientific journal)

    　View Summary

    <p>This paper presents the development of a new method for the estimation and resolution of body occlusion using deep learning for an advanced intelligent video surveillance system. A generative adversarial network is used to estimate and reconstruct an image of a hidden part of the human body. Furthermore, an alternative learning approach using 3DCG that was developed in our previous study is adopted to create a large dataset for deep learning. Experimental results indicate that the proposed method performs well in the estimation of hidden parts of the human body using images of actual people.</p>
