Taking Lifelog Videos and Managing Impressive Scenes

For the purpose of retrieving impressive scenes from lifelog videos based on facial expression recognition, an effective equipment to take facial videos is developed in this paper. The important advantage of this equipment is that it is able to take facial videos without excessive fatigue. In addition, we implemented an emotional scene management system. It provides the functions to store facial videos to a video database and to retrieve and display emotional scenes through Web browsers. In order to measure the retrieval performance of emotional scenes, a retrieval experiment was conducted. It was experimentally shown that about 78.6% of the emotional scenes were retrieved successfully.
