| Abstract(in English) | When detecting objects in images by which classifying many location hypotheses, it is necessary to define aspect ratio and scale of detection window in advance. In this paper, we construct a model of size distribution of objects in images, and revealed that the size of foods in images taken for recording dietary follows a log-normal distribution. We apply this characteristic to defining parameters of selective search, the method of generating object hypotheses, and result in high Mean Average Best Overlap in spite of small number of object hypotheses when using FoodLog image dataset. |
