    • Hierarchal modeling is used to distinguish one state (26, 28, 32, 34, 38, 40, 44, 46) or class from three or more classes. In a first stage, a normal (26) or other class is distinguished from a diseased (28) or other groups of classes. If the results of the first stage classification indicate diseased (28) or data within the groups of different classes, a subsequent stage of classification is performed. In a subsequent stage of classification, the data is classified to distinguish one or more other classes (32, 34, 38, 40, 44, 46) from the remaining classes. Using two or more stages, medical information is classified by eliminating one or more possible classes in each stage to finally identify a particular class (26, 28, 32, 34, 38, 40, 44, 46) most appropriate or probable for the data.
    • 分层建模用于将一个状态(26,28,32,34,38,40,44,46)或类与三个或更多个类别区分开。 在第一阶段,正常(26)或其他类别与患病(28)或其他类别的组不同。 如果第一阶段分类的结果表示患病(28)或不同类别的组内的数据,则进行后续分类阶段。 在分类的后续阶段,数据被分类以区分一个或多个其他类别(32,34,38,40,44,46)与其余类别。 使用两个或更多个阶段,通过消除每个阶段中的一个或多个可能的类别来分类医学信息,以最终确定最合适或可能的数据的特定类别(26,28,34,34,38,40,44,46) 。

    • A method for classifying features in a digital medical image includes providing a plurality of feature points in an N-dimensional space, wherein each feature point is a member of one of two sets, determining a classifying plane that separates feature points in a first of the two sets from feature points in a second of the two sets, transforming (32) the classifying plane wherein a normal vector to said transformed classifying plane has positive coefficients and a feature domain for one or more feature points of one set is a unit hypercube in a transformed space having n axes, obtaining (33) an upper bound along each of the n-axes of the unit hypercube, inversely transforming (34) said upper bound to obtain a new rule containing one or more feature points of said one set, and removing (35) the feature points contained by said new rule from said one set
    • 一种用于对数字医学图像中的特征进行分类的方法包括在N维空间中提供多个特征点,其中每个特征点是两组中的一个的成员,确定分类平面, 从两组中的第二组中的特征点组成两组,变换(32)分类平面,其中向所述变换的分类平面的法向量具有正系数,并且一组中的一个或多个特征点的特征域是单位超立方体 具有n轴的变换空间,获得(33)沿着单位超立方体的每个n轴的上限,逆向变换(34)所述上限以获得包含所述一个集合的一个或多个特征点的新规则, 以及从所述一组中去除(35)所述新规则所包含的特征点
