Comparison of Known Food Weights with Image-Based Portion-Size Automated Estimation and Adolescents Self-Reported Portion Size

摘要

BackgroundDiet is a critical element of diabetes self-management. An emerging area of research is the use of images for dietary records using mobile telephones with embedded cameras. These tools are being designed to reduce user burden and to improve accuracy of portion-size estimation through automation. The objectives of this study were to (1) assess the error of automatically determined portion weights compared to known portion weights of foods and (2) to compare the error between automation and human.
