Features for Measuring Progression of Gastric Atrophy Focused on Areae Gastricae in Gastric X-ray Images

Abstract

This paper presents image features for evaluating the progression of gastric atrophy from gastric X-ray images. In the proposed method, after the diagnostic area is extracted, the areas where the gastric wall looks rough are extracted according to the diagnostic index for reading the atrophy. Then, the proposed features measure the number and the size of the rough areas in the diagnostic area. In the experiments, the performance of the proposed features were examined with 84 images. The experimental results showed that the features are effective well to evaluate the progression of gastric atrophy.
