We can observe Dots in dermoscopy images of pigmented skin lesions. Dots are dark small circular areas on pigmented skin lesion. Doctors take notice when Dots exist on border of tumor, count the Dots, and pay attention those scatter of size. This paper presents automatic detection for Dots. For the detection, we use closing operation, one of the morphological filters. But it has some faults to pick up Dots. That detects not only Dots but also edge of other structures. We improve the filter and compare it with classic one. An application of closing operation can solve problems.
