选择用于图像分割的解剖变型模型
摘要：
本发明涉及一种用于分割图像中对象的系统（100），包括第一调适器（110），其用于将用于分割所述对象的第一模型调适到所述图像，分析器（115），其用于基于所述经调适的第一模型而从所述图像中提取出特征，选择器（120），其用于基于从所述图像中提取出的所述特征来从用于分割所述对象的多个模型中选择用于分割所述对象的第二模型，其中所述第二模型包括所述对象的额外细节，初始化器（125），其用于基于所述经调适的第一模型和/或从所述图像中提取出的所述特征来初始化所述第二模型，以及第二调适器（130），其用于将所述经初始化的第二模型调适到所述图像。基于所述经调适的第一模型从所述图像提取出的所述特征帮助所述系统（100）从用于分割所述对象的多个模型中选择用于分割所述对象的所述第二模型。所述经调适的第一模型和/或所述提取出的特征也用于初始化所述第二模型。由于所述第二模型包括所述对象的所述额外细节，因此使用所述第二模型获得的分割结果比使用所述第一模型获得的分割结果更加完整。此外，基于所述经调适的第一模型和/或所检测到的特征的所述第二模型的初始化改善了第二模型调适的精确性。
摘要（英）：

The invention relates to a system (100) for segmenting an object in an image, comprising a first adapter (110) for adapting a first model for segmenting the object to the image, an analyzer (115) for extracting a feature from the image based on the adapted first model, a selector (120) for selecting a second model for segmenting the object from a plurality of models for segmenting the object, based on the feature extracted from the image, wherein the second model comprises additional detail of the object, an initializer (125) for initializing the second model based on the adapted first model and/or the feature extracted from the image, and a second adapter (130) for adapting the initialized second model to the image. The features extracted from the image based on the adapted first model help the system (100) to select the second model for segmenting the object from a plurality of models for segmenting the object. The adapted first model and/or the extracted features are also used for initializing the second model. Because the second model comprises the additional detail of the object, the segmentation result using the second model is more complete than the segmentation result obtained using the first model. Moreover, the initialization of the second model based on the adapted first model and/or the detected features improves the accuracy of the second model adaptation.
