Outline of Final Research Achievements

In the field of image processing and image recognition, a lot of techniques using big data have been proposed. However, it is difficult to collect enough reliable data in many cases. In this study, we developed a method for constructing a model that can generate image data by considering the structure. An image is divided into regions according to its structure. Then a model is constructed for each region. A whole model is constructed by combining all the models. Experimental results using the proposed model show its effectiveness.
