We report on a method for summarizing a video which recorded the process of cooking by an individual. In recent years, life-log which records the daily life of an individual has been attracting attention. However, since life-log is recorded over a long time, the amount of data is huge. In this report, we focus on cooking which is a creative activity in daily life, and we propose a method for summarizing a cook-log video which recorded the process of cooking by an individual. A cook-log video can not only be used as a kind of life-log, but it can also be able to be provided on the Internet as a reference for other people to cook. Thus, summarizing a cook-log video enables more efficient search and browsing. The proposed method detects the state sections and the repetitious sections as temporal redundant sections, and summarizes the cook-log video by removing them. We conducted a section detection experiment using an actual cook-log. A precision of 0.98 and a recall of 0.99 were obtained for detecting the state section, and a precision of 0.62 and a recall of 0.92 were obtained for detecting the repetitious section.}, pages = {55--60}, title = {時間的冗長性の除去による調理履歴映像の要約}, volume = {112}, year = {2012} }
