Food Sustenance Estimation Using Food Image
The upcoming generation is at high risk of developing many health issues like heart diseases, metabolic diseases and other life-threatening problems with high mortality as a consequence of obesity due to intake of unhealthy food which is totally deviated from a normal balanced diet with appropriate calories, proteins, vitamins and carbohydrates. In this work, the nutrient intake is calculated using food image. Our system provides efficient segmentation algorithms for separating food items from the plate. The given 2D image of food is converted into 3D image by generating its depth map for volume generation and color, texture and shape features are extracted. These features are fed as input into multi-class support vector machine classifier for learning. The learning phase involves training of various mixed and non mixed food items. The testing phase includes query image segmentation and classification for identifying the type of food and then finding calories using the nutrition data table. We have also estimated the ingredient and decay of food items. Our result shows accurate calorie estimation for various kinds of food items.
