The human stomach i s difficult to recognize i n an X-ray because of its elasticity. Global information of the stomach or are-of similar density is required for easy recognition The authors have developed a method for r i d i n g the b o r d a line of a stomach by using computational geometry. The method i s composed of three steps. In the f i s t step, the(More)
We present a novel visualization method for finding care factors in variance analysis. The analysis has two stages: first stage enables users to extract a significant variance, and second stage enables users to find out a critical care factors of the variance. The analysis has been validated by using synthetically created inpatient care processes. It was(More)
