    • The invention relates to a detection method (300) of detecting a boundary in a second image data from an image dataset on the basis of a reference contour in a first image data from the image dataset, the detection method (300) comprising a generating step (320) for generating a reference profile using the first image data on the basis of a qualifying characteristic, the reference profile comprising a reference profile node defined on the basis of the reference contour, a selecting step (330) for selecting a target profile using the second image data on the basis of the reference profile, and a mapping step (335) for mapping the reference profile node into the second image data on the basis of the target profile, thereby detecting the second boundary. A reference profile generated on the basis of a qualifying characteristic is more accurate in detecting the boundary in the second image than an arbitrarily generated reference profile. Hence, the detection method (300) of the current invention is more accurate in detecting a boundary in a second image data from an image dataset on the basis of a reference contour in a first image data from the image dataset.
    • 本发明涉及一种检测方法(300),该检测方法(300)根据来自图像数据集的第一图像数据中的参考轮廓从图像数据集检测第二图像数据中的边界,检测方法(300)包括生成步骤 (320),用于基于限定特性使用所述第一图像数据生成参考轮廓,所述参考轮廓包括基于所述参考轮廓定义的参考轮廓节点;选择步骤(330),用于使用 基于参考简档的第二图像数据,以及用于基于目标轮廓将参考轮廓节点映射到第二图像数据中的映射步骤(335),从而检测第二边界。 基于限定特性生成的基准曲线在检测第二图像中的边界方面比任意生成的参考轮廓更准确。 因此,根据来自图像数据集的第一图像数据中的参考轮廓,本发明的检测方法(300)更精确地检测来自图像数据集的第二图像数据中的边界。
