Popis: Background Food object recognition systems present an attractive and useful research field since they enable objective measurements of eating activity. This feature is helpful and welcome in many dieting related instances, especially for managing health conditions or for analyzing eating patterns of research subjects. Scope and approach We evaluate current food object recognition systems that were implemented on a mobile device. The evaluation was provided by analysing each particular system through its food recognition process. The whole recognition process was divided into 6 distinct stages: image acquisition, image processing, image segmentation, feature extraction, image classification, and volume estimation. Key findings and conclusions Through the analysis, the authors provide a categorization of mobile food recognition systems: recorder systems, suggester systems, and clinical responders. Each group is aimed at a different scenario which helps to identify features a particular system should focus its development on.
