基于曲线演化的CT颅骨外轮廓提取
Outer contour extraction of CT skull based on curve evolution
摘要
Abstract
When reconstructing three-dimensional model of a skull based on contour lines, it was one of the primary problems to extract the single-deck and outer contour of the skull region accurately and effectively. For the difficulty of extracting such contour from the complex skull shape, this paper presented a method based on curve evolution. It firstly required to segment the image by a threshold to generate the skull region, and then initialized a single-deck and closed curve containing the region. Furthermore, evolved the curve using a novel differential equation. Lastly, extracted outer contour of the skull region. The results of experiences indicate that this method can automatically process the skull CT image, and accurately extract the single-deck and outer contour of the skull, at the same time, efficiently solve the problem of extracting the single-deck and outer contour of the skull.关键词
