Visual Aware Hierarchy Based Food Recognition [article]

Runyu Mao, Jiangpeng He, Zeman Shao, Sri Kalyan Yarlagadda, Fengqing Zhu
2020 arXiv   pre-print
, then a multi-task CNN model is proposed to perform the classification task based on the visual aware hierarchical structure.  ...  In this work, we propose a new two-step food recognition system that includes food localization and hierarchical food classification using Convolutional Neural Networks (CNNs) as the backbone architecture  ...  However, our proposed method is agnostic about the underlying CNN model used, so we want to show the improvement of the classification accuracy based on a hierarchical structure of the class labels.  ...
