    • A method and system correlate candidate information and provide batch classification of a number of related candidates. The batch of candidates may be identified from a single data set. There may be internal correlations and/or differences among the candidates. The candidates may be classified taking into consideration the internal correlations and/or differences. The locations (104) and descriptive features (106) of a batch of candidates may be determined. In turn, the locations and/or descriptive features determined may be used to enhance the accuracy of the classification of some or all of the candidates within the batch (108). In one embodiment, the single data set analyzed is associated with an internal image of patient (102) and the distance between candidates is accounted for. Two different algorithms may each simultaneously classify all of the samples within a batch, one being based upon probabilistic analysis and the other upon a mathematical programming approach. Alternate algorithms may be used.
    • 一种方法和系统将候选信息相关联并提供一些相关候选者的批次分类。 可以从单个数据集中识别该批候选。 候选人之间可能存在内部相关性和/或差异。 候选人可以考虑内部相关性和/或差异进行分类。 可以确定一批候选的位置(104)和描述特征(106)。 反过来,所确定的位置和/或描述性特征可以用于提高批次(108)内部分或全部候选者的分类的准确性。 在一个实施例中,分析的单个数据集与患者(102)的内部图像相关联,并且考虑候选者之间的距离。 两种不同的算法可以各自同时对批次内的所有样本进行分类,一种基于概率分析,另一种基于数学规划方法。 可以使用替代算法。

    • 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
