Image segmentation is an important topic in digital image processing and can be found in various field of images research. One of them is medical image segmentation in the medical field. Edge of image segmentation of lung CT scan is an alternative step in medical lung images processing, which the result can be continued to be used to detect the presence of nodules that are useful as an auxiliary parameter in detecting lung disease like cancer. In this study, edge of image segmentation of lung CT scan is using chain code and mathematical morphology operations. The function of chain code in this study is to detect edge of lung in CT image, whereas the morphology operations are used to enhancement the shape of image. This study showed that the use of chain code and morphological operations can provide a smooth edge of lung CT scan image segmentation. The smooth detail on the edge of the lung CT scan can provide important information such as the boundary of an areas or object within the image. Mathematical morphology operations haven’t been success applied to all images, the percentage of success is 76.6% and percentage of success to eliminate noise in lung CT images is equal to 86.7%.Kata kunci:Segmentasi citra; CT-Scan paru-paru; Chain Code; Matematika Morfologi
