For nutrition practitioners and researchers, assessing dietary intake of children and adults with a high level of accuracy continues to be a challenge. Developments in mobile technologies have created a role for images in the assessment of dietary intake. The objective of this review was to examine peer-reviewed published papers covering development, evaluation and/or validation of image-assisted or image-based dietary assessment methods from December 2013 to January 2016. Images taken with… 

Accuracy and Cost-effectiveness of Technology-Assisted Dietary Assessment Comparing the Automated Self-administered Dietary Assessment Tool, Intake24, and an Image-Assisted Mobile Food Record 24-Hour Recall Relative to Observed Intake: Protocol for a Randomized Crossover Feeding Study (Preprint)

This study compares the accuracy, acceptability, and cost-effectiveness of 3 technology-assisted 24-hour dietary recall methods relative to observed intake across 3 meals to inform the selection of dietary assessment methods in future studies on nutrition surveillance and epidemiology.

Feasibility of Reviewing Digital Food Images for Dietary Assessment among Nutrition Professionals

Accuracy of nutrition professionals in reviewing food images could be further improved with training on better perception of portion sizes from images.

Image-Based Food Classification and Volume Estimation for Dietary Assessment: A Review

After a comprehensive exploration, it is found that integrated dietary assessment systems combining with different approaches could be the potential solution to tackling the challenges in accurate dietary intake assessment.

Active Image-Assisted Food Records in Comparison to Regular Food Records: A Validation Study against Doubly Labeled Water in 12-Month-Old Infants

Without validation, commercially available software to aid in the volume estimations, food item identification, and automation of the image processing, image-assisted methods remain a more costly and burdensome alternative to regular FRs in infants.

Feasibility of wearable camera use to improve the accuracy of dietary assessment among adults

Reporting of energy and nutrient intake may be enhanced when a traditional method of dietary assessment, the 24-h recall, is assisted by a wearable camera.

An Active Image-Based Mobile Food Record Is Feasible for Capturing Eating Occasions among Infants Ages 3–12 Months Old in Hawai‘i

An image-based dietary assessment method using a mobile app was found to be feasible for surrogate reporters to record an infant’s food and beverage intake throughout the day.

Assessment of Dietary Intake Using Food Photography and Video Recording in Free-Living Young Adults: A Comparative Study

Improved Wearable Devices for Dietary Assessment Using a New Camera System

There is a considerable risk of missing important dietary data owing to the common use of rectangular image screen and fixed camera orientation, and two designs of a new camera system to reduce data loss by generating circular images using rectangular image sensor chips are presented.

Applying Image-Based Food-Recognition Systems on Dietary Assessment: A Systematic Review

An extended critical literature overview of image-based food-recognition systems (IBFRS) combining a camera of the user's mobile device with computer vision methods and publicly available food datasets (PAFDs) is presented.



Image-assisted dietary assessment: a systematic review of the evidence.

Evaluation of a Mobile Phone Image-Based Dietary Assessment Method in Adults with Type 2 Diabetes

The performance and feasibility of the NuDAM to assess energy and macronutrient intake in a small sample are demonstrated and an evaluation in a larger group of adults with type 2 diabetes mellitus is required.

The Use of Mobile Devices in Aiding Dietary Assessment and Evaluation

A novel mobile telephone food record that will provide an accurate account of daily food and nutrient intake and the approach to image analysis that includes the segmentation of food items, features used to identify foods, a method for automatic portion estimation, and the overall system architecture for collecting the food intake information are described.

Image enhancement and quality measures for dietary assessment using mobile devices

To address the color consistency problem, this paper describes illumination quality assessment methods implemented on a mobile device and three post color correction methods.

Novel Technologies for Assessing Dietary Intake: Evaluating the Usability of a Mobile Telephone Food Record Among Adults and Adolescents

A majority of both age groups were able to follow the defined set of skills; however, adults were less efficient when using the mobile telephone food record.

How Willing Are Adolescents to Record Their Dietary Intake? The Mobile Food Record

The adolescents’ experiences with and feedback about the mFR highlighted the importance of increased training, reminders, entertainment (eg, games), and training with practice in using the device to capture complete dietary intake as part of their active lifestyles.

Wearable cameras can reduce dietary under-reporting: doubly labelled water validation of a camera-assisted 24 h recall.

TEE and EI assessed by the MP24 and MP24+SC methods were compared and the increase in EI was predominantly from the addition of 265 unreported foods as revealed by the participants during the image review.

A mobile phone user interface for image-based dietary assessment

A user interface for a mobile telephone food record that relies on taking images, using the built-in camera, as the primary method of recording and keeping the user interface easy to use is presented.

A pilot study to determine whether using a lightweight, wearable micro-camera improves dietary assessment accuracy and offers information on macronutrients and eating rate

Use of the micro-camera images in conjunction with food diaries improves the accuracy of dietary assessment and provides valuable information on macronutrient intake and eating rate.
