摘要： A multilevel image segmentation technique using graph cuts is disclosed. A reduced resolution image is generated from a full resolution image which is to be segmented. The reduced resolution image is then segmented in order to identify a boundary between an object and a background within the image. The identified boundary then identifies a portion of an increased resolution image which is segmented in order to refine the earlier identified boundary. The steps may be iterated for successively increasing image resolutions in order to refine the boundary as required by a particular application. An initial identification of object and background portions of the image may be provided as input by a user. Alternatively, a user may identify only the object portion, and the background portion may be automatically determined.

摘要： An intuitive user interface is provided for endoscopic view visualization. The user interface may permit individual or simultaneous navigation through images displayed in an endoscopic view window, a three dimensional overview window, and a multi-planar reformatted window. An operation performed directly on one of the windows may commence the navigation. The endoscopic view window may be divided into a plurality of sub-regions, each sub-region having a corresponding navigation function. The endoscopic view window and the three dimensional overview window may have corresponding icons related to a single location in corresponding images being displayed. The corresponding icons may be color coded to facilitate intuitive alignment of the corresponding images displayed in the different windows. The three dimensional overview window may have a geometric icon to facilitate intuitive alignment of the corresponding images. The multi-planar reformatted window may permit spherical navigation through the images displayed.
摘要翻译： 为内窥镜视图可视化提供直观的用户界面。 用户界面可以允许通过在内窥视图窗口，三维概览窗口和多平面格式化窗口中显示的图像进行单独或同时导航。 在其中一个窗口上直接执行的操作可以开始导航。 内窥视图窗口可以被划分为多个子区域，每个子区域具有相应的导航功能。 内窥视图窗口和三维概览窗口可以具有与正在显示的相应图像中的单个位置相关联的相应图标。 对应的图标可以是颜色编码的，以便于在不同窗口中显示的相应图像的直观对准。 三维概览窗口可以具有几何图标以便于对应图像的直观对准。 多平面重新格式化的窗口可以允许通过显示的图像进行球形导航。
