| Research Abstract |
In order to retrieve impressive scenes from lifelog videos, a retrieval system of emotional scenes, which is considered to be impressive, has been developed in this research. The retrieval system detects emotional scenes based on facial expression recognition. In addition, a lifelog video database including video sequences of daily life and the information about emotional scenes contained in the video sequences has been constructed. By using the database, emotional scene retrieval experiments were conducted to evaluate the retrieval performance. Since the video scenes including smile and/or laughter will be impressive, the retrieval experiments are focused on retrieving such video scenes. The precision of the scene retrieval in this experiment was more than 90%.
