A method for obtaining the contour of a stomach from radiograms is presented. The method forms a part of a fully automated interpretation system designed for the diagnosis of a large number of radiograms of the stomach obtained, for example, in mass surveys. First, major figures are extracted by a dynamic threshold method and finally the image of the stomach only is obtained by labeling and extraction of the figure with the largest area. The contour is then obtained by a boundary following algorithm. Another program was written to obtain the medial axis of the stomach and to eliminate the image of the intestine using the methods of skeletoning, distance transformation and inverse distance transformation. The output may be used for the recognition of global characteristics and as a guideline for obtaining the accurate contour to be used in methods based on the analysis of contour irregularities.
