Initial closed curve for active contour model on mesh = 메쉬 모델 상의 동적 윤곽선 모델을 위한 초기 폐곡선 생성

다국어 초록 (Multilingual Abstract)

The accurate margin line extraction is a crucial process in computer-aided orthodontics. Margin line is boundary line of treatment region. Though curvature field is traditionally used for detect feature line, different shapes and scanning noises make hard to detect margin line automatically. Thus current dental CAD systems mostly require the user interactive definition of points by the user. So, we also use interactive defined starting points by the user. In medical image processing, active contour model is used to extract feature line. However it doesn’t work when initial curve is improper. To solve this problem, this paper proposes a novel closed curve initialization algorithm that makes initial curve on mesh by using starting points. Some experiments show our initialization method is robust and fast.
