A deliciousness information extraction method by controlling of image information

It is difficult to analyze how human feels deliciousness by seeing served food because many factors affect to judgment of deliciousness. Human recognizes and evaluates deliciousness of the food from many points of view. In this paper, we propose a method to extract the points of view and factors that recognize deliciousness. Images which are reduced resolution to control information of the image were provided to the subjects. At low resolution images, we cannot see many factors which can be recognized at higher resolution, and we judge deliciousness from the only factor which can be recognized. We show the effectiveness of our proposed method for applying the box lunch.
