Abstract :
For improving detectability of the gastric lesions in the X-ray examinations, the computer image processing methods are studied in radiographs of gastric cancer lesions. We propose an adaptive differential filters to the edge detection. Moreover, the level set method is adopted to the segmentation. Furthermore, the numerical examples are carried out, using the case radiograph of the gastric intestines medical picture database produced by National Kyushu Cancer Center.
