摘要

This paper presents a detection method of chronic gastritis from gastric X-ray images. The conventional method cannot detect chronic gastritis accurately since the number of non-gastritis images is overwhelmingly larger than the number of gastritis images. To deal with this problem, the proposed method performs the detection of chronic gastritis by using Deep Autoencoding Gaussian Mixture Models (DAGMM) which is an anomaly detection approach. DAGMM enables construction of chronic gastritis detection model using only non-gastritis images. In addition, DAGMM is superior to conventional anomaly detection methods since the models of dimensionality reduction and density estimation can be learned simultaneously. Therefore, the proposed method realizes accurate detection of chronic gastritis by utilizing DAGMM.
