Abstract

Obesity is increasing globally. Obesity brings with it many chronic conditions. There has been increasing research in the use of ICT interventions to combat obesity using food logging and image calorie analysis. These interventions allow users to document their calorie intake to help promote healthy living. However using food logs may lead to inaccurate readings as the user may incorrectly calculate portion size when recording nutritional information. This paper discusses the use of image nutritional analysis techniques to ascertain a more accurate calorie reading from photographs of food items. The methods employed involve determining a ground truth data set by correlating weight of a food item with its area in cm2. This dataset could then be plotted on a regression model and used to determine calorie content of future portions. The proposed system uses a semi-automated approach to allow users to manually draw around the food portion using a polygonal tool. Results show that the application achieved a reasonable accuracy in predicting the calorie content of food item portions with a 11.82% percentage error.
