| Outline of Final Research Achievements |
In this study, to reduce the burden of food recording, we have advanced the personalization of the food recording technology based on image recognition, and built foundation of technology for recognizing meal photos and analyzing the records of specific persons. Based on these technologies, we have developed and are operating a new food recording tool suitable for nutritional guidance and food surveys. We have achieved the following research results. (1) Personalized food image recognition, (2) Personalized food recognition considering time dependency and item dependency, (3) Boosting personalized food recognition by sharing data with others, (4) Prediction and visualization of ingredient categories, (5) Development, release, operation, and improvement of the new FoodLog (FoodLog_Athl) (6) Verification of the new FoodLog through the use of nutritional guidance (7) Survey of diet and health by the new FoodLog.
