Six of the ten leading causes of death in the United States can be directly linked to diet. Dietary assessment, the process of determining what someone eats during the course of a day, is essential for understanding the link between diet and health. We are developing imaging based tools to automatically obtain accurate estimates of what foods a user consumes. Accurate food segmentation is essential for identifying food items and estimating food portion sizes. In this paper, we present a quantitative evaluation of automatic image segmentation methods for food image analysis used for dietary assessment. The experiments indicate that local variation is more suitable for food image segmentation in general dietary assessment studies where the food images acquired have complex background.</p>","PeriodicalId":91891,"journal":{"name":"ISSCS 2013 : International Symposium on Signals, Circuits and Systems : 11-12 July, 2013, Iasi, Romania : program.

The number of unknown parameters quickly approaches the number of measurements and hence, structural assumptions on the ionosphere must be made, in time, frequency, and space. Using general models for the second-order statistics, we propose to use maximum a posteriori (MAP) estimators combined with Karhunen-Loeve basis functions. The resulting estimation algorithm is shown in simulated LOFAR data to be superior to currently considered techniques. A significant advantage is that it is robust to overestimation of the number of free parameters.","PeriodicalId":91891,"journal":{"name":"ISSCS 2013 : International Symposium on Signals, Circuits and Systems : 11-12 July, 2013, Iasi, Romania : program.
