FOODCAM: A Novel Structured Light-Stereo Imaging System for Food Portion Size Estimation [PDF]
Sensors, 2022 Imaging-based methods of food portion size estimation (FPSE) promise higher accuracies compared to traditional methods. Many FPSE methods require dimensional cues (fiducial markers, finger-references, object-references) in the scene of interest and/or ...

The accuracy of portion size estimation using food images and textual descriptions of portion sizes: an evaluation study [PDF]
Journal of Human Nutrition and Dietetics, 2021 AbstractBackgroundInaccurate self‐report of portion sizes is a major cause of measurement error in dietary assessment. To reduce this error, different portion size estimation aids (PSEAs) have been developed, including food images (image based, IB‐PSE) and textual descriptions of portion sizes (text‐based, TB‐PSE).

Effect of Gradually Reduced Portion Size Estimation Training on Portion Size and Daily Energy Intake Estimation Accuracy [PDF]
Curr Dev Nutr, 2022 OBJECTIVES: We examined the effect of gradually reduced guidance and feedback on portion size and daily reported energy intake (EI) estimation accuracy. We hypothesized that training would result in relatively accurate portion size estimation at a group level and that portion sizes would be most accurately estimated for solid foods compared with ...

Literacy, numeracy, and portion-size estimation skills. [PDF]
Am J Prev Med, 2009 Portion-size estimation is an important component of weight management. Literacy and numeracy skills may be important for accurate portion-size estimation. It was hypothesized that low literacy and numeracy would be associated with decreased accuracy in portion estimation.A cross-sectional study of primary care patients was performed from July 2006 to ...
