Data Set for PlateMate



This data set includes 16 out of 18 images used in the evaluation of the accuracy of PlateMate. Included is also a spreadsheet providing ground truth nutritional information for a meal shown in each photo (as reported by a preparer or manufacturer) as well as PlateMate estimates and estimates by 3 expert nutritionists. We also include estimates provided by the MealSnap iPhone app (evaluated in April of 2011).

This data set accompanies the following paper:

Jon Noronha, Eric Hysen, Haoqi Zhang, and Krzysztof Z. Gajos. PlateMate: Crowdsourcing Nutrition Analysis from Food Photographs. In Proceedings of the 24th annual ACM symposium on User interface software and technology, UIST '11, pages 1-12, New York, NY, USA, 2011. ACM.

Example of a meal photograph used in the evaluation of accuracy of PlateMate estimates

The data set is provided as a single .zip file. It contains a directory with 16 food photographs and an Excel spreadsheet containing the analysis results. Note that some photographs present complex meals: PlateMate divides the analysis of such meals into analyses of individual component foods. For example, with the photograph shown here, PlateMate will start by dividing the meal into three components: pulled chicken sandwich, broccoli and potato wedges. The Excel spreadsheet includes a separate column for each food shown in each of the photographs. The comparisons to other systems, however, are performed at the level of entire meals.
