Outline of Final Research Achievements

We have investigated a smartphone based technology of self-monitoring of dietary habit for health promotion. Conventional self-monitoring methods have been such a way that a person writes down on a sheet every food he/she eats. However, writing description of every food items and their amounts requires huge efforts, and he/she feels difficulty to continue recording and change his/her eating habit. We have developed a multimedia food recording tool, FooLog, by which we can interactively describe our food content by help of image retrieval. By making use of image processing, we can much reduce our efforts in food recording. In this project, we made significant improvement of FoodLog system and conduct its evaluation and verification.
