Abstract

In recent years, an increasing number of people have been suffering from over-weight, indicating the importance of a balanced dietetic lifestyle. Researches in nutrition and oral health have raised the importance of not only calorific consumption, but also eating habits quality such as the regularity of meals, eating speed, and food texture. A new model for the estimation of food texture by analyzing chewing sound collected from a wearable sensor is presented in this paper. The proposed model combining effective sound features extraction and classification methods make it possible to estimate quantitatively detailed texture of food a person is eating. The model has been implemented and shown being efficient (more than 90% accuracy) to estimate three food texture indices at eight detailed levels for each, with little influence of individual chewing differences.
