    • The methods and apparatus including computer program products, implementing and using techniques for masking and extracting a foreground portion from a background portion of a digital image (fig. 1). In the method, a first input defining a first border region is received, which includes at least a part of the foreground portion and at least a part of the background portion in first digital image (fig. 3a). A second input defining a second border region is received, which includes at least a part of the foreground portion and at least a part of the background portion in a second digital image (fig. 6). An intermediary border region is interpolated for an image intermediary in time of the first and second digital images and the first (fig. 7), second and intermediary border regions are used for masking the foreground portion from the background portion in the digital video (fig. 8).

    • The invention relates to a method of separating a searched object from a digital microscope image, which comprises a plurality of picture elements and reproduces a biological material. The method is characterized by the steps of selecting in the image at least a first picture element, the appearance of which is different from that of expected picture elements in the searched object, said at least one picture element constituting an initial quantity; assigning to at least a first subset of the remaining picture elements in the image object similarity values; calculating object likelihood values, on the basis of said initial quantity and said object similarity values, for at least a subset of the picture elements in the image; and separating the searched object on the basis of the object likelihood values.
    • 本发明涉及一种从数字显微镜图像中分离检索对象的方法,该数字显微镜图像包括多个图像元素并再现生物材料。 该方法的特征在于,在图像中至少选择出现与搜索对象中的期望图像元素不同的第一图像元素的步骤,所述至少一个图像元素构成初始量; 向所述图像对象相似度值中的剩余图像元素的至少第一子集分配; 对于图像中的图像元素的至少一个子集,基于所述初始量和所述对象相似度值计算对象似然值; 以及基于对象似然值分离所搜索的对象。

    • A data processing unit receives a reference image (IMG1 3D ) of a deformable physical entity, a target image (IMG2 3D ) of said physical entity, and a first region of interest (ROI1 3D ) defining a first volume in the reference image (IMG1 3D ) representing a reference image element. The reference image (IMG1 3D ), the target image (IMG2 3D ) and the first region of interest (ROI1 3D ) all contain 3D datasets. In response to user commands (c1; c2), the data processing unit defines a first contour (C1 2D ) in a first plane through the target image (IMG2 3D ), which is presented to a user via a display unit together with graphic data reflecting the reference image (IMG1 3D ), the target image (IMG2 3D ) and the first region of interest (ROI1 3D ). The first contour (C1 2D ) is aligned with at least a portion of a first border (IEB1) of a target image element (IE 3D ) in the target image (IMG2 3D ). The target image element (IE 3D ) corresponds to the reference image element in the reference image (IMG1 3D ). Based on the first contour (C1 2D ), the target image (IMG2 3D ) and the first region of interest (ROI1 3D ); the data processing unit determines a second region of interest (ROI2 3D ) defining a second volume in the target image (IMG2 3D ).
    • 数据处理单元接收可变形物理实体的参考图像(IMG13D),所述物理实体的目标图像(IMG23D)和定义参考图像(IMG13D)中的第一体积的第一感兴趣区域(ROI13D)(IMG13D) 参考图像元素。 参考图像(IMG13D),目标图像(IMG23D)和第一感兴趣区域(ROI13D)都包含3D数据集。 响应于用户命令(c1; c2),数据处理单元通过目标图像(IMG23D)在第一平面中定义第一轮廓(C12D),其通过显示单元与反映 参考图像(IMG13D),目标图像(IMG23D)和第一感兴趣区域(ROI13D)。 第一轮廓(C12D)与目标图像(IMG23D)中的目标图像元素(IE3D)的第一边界(IEB1)的至少一部分对准。 目标图像元素(IE3D)对应于参考图像(IMG13D)中的参考图像元素。 基于第一轮廓(C12D),目标图像(IMG23D)和第一感兴趣区域(ROI13D); 数据处理单元确定在目标图像(IMG23D)中定义第二卷的感兴趣的第二区域(ROI23D)。
