Center node: "exploring food detection using cnns"
  Abstract: One of the most common critical factors directly related to the cause of a chronic disease is unhealthy diet consumption. Building an automatic system for food analysis could enable a better understanding of the nutritional information associated to the food consumed and thus, help taking corrective actions on our diet. The Computer Vision community has focused its efforts on several areas involved in visual food analysis such as: food detection, food recognition, food localization, portion estimation, among others. For food detection, the best results in the state of the art were obtained using Convolutional Neural Networks. However, the results of all different approaches were tested on different datasets and, therefore, are not directly comparable. This article proposes an overview of the last advances on food detection and an optimal model based on the GoogLeNet architecture, Principal Component Analysis, and a Support Vector Machine that outperforms the state of the art on two public food/non-food datasets.
