Abstract (in Japanese) (See Japanese page) 
(in English) In the field of medical imaging such like computed tomography analysis, it is difficult to prepare a sufficient amount of labeled data for learning, and there exists bias in the number of classes.
Applying such data into a learning machine, we may obtain .

In order to overcome this problem, we propose a new data augmentation framework for case image data set of diffuse lung disease.
Specifically, we propose a method of decomposing learning data images in Fourier space and combining amplitude characteristics and phase characteristics among other classes for data augmentation.

As a result of the learning of the lesion identification problem in Deep Convolutional Neural Network using this method, the accuracy was improved compared with the conventional method such as normal linear transformation and the method proposed in recent years.
