    • A system for delineating partially- or fully-bounded areal regions of a map utilizes deformable templates, which it dynamically expands and contorts to conform to the boundaries of the regions. The system segments the map into a number of cells, with each cell relating, for example, to a pixel. The system then defines an "energy" field for the floor plan by assigning cells corresponding to boundary edges predetermined minimum energy values, cells corresponding to boundary interiors predetermined maximum energy values, and each non-boundary cell an energy value defined by the distance of the cell from the closest boundary edge cell. The system then iteratively manipulates a template over a selected region of the floor plan in an attempt to minimize the "potential" of the template, which is defined by a potential function that includes a "total energy score" and various size and test terms that encourage desired template deformations. The system determines the total energy score, by (i) scan converting the template sides, (ii) weighting the energy values of the cells through which the sides pass based on the lengths of the sides passing through the cells, and (iii) summing the scores. After determining the potential for all possible new locations for each of the vertices, the system selects next locations for each of the vertices and, as necessary, moves the vertices to these next locations to complete an iteration. At various times, the system raises the energy field and updates the template by altering the number of vertices. The system ends its manipulations of the template when it has performed a predetermined number of iterations or, in an energy field at its ceiling values, either the template vertices do not move between iterations or the potential of the template does not change. A user may then edit the template to conform the template more closely to the selected region. A user may also specify certain constraints on template deformation. In response, the system uses a modified potential function for controlling the deformation of the template.

    • Apparatus for determining the structure of a hypermedia document containingext and graphics that are to be laid out on several linked pages includes a system that specifies the assignment of text and graphics to pages and the links between the pages via a reduction to graph partitioning and the use of optimization techniques for graph partitioning. In one embodiment, display items and relations between these display items are listed along with a measure of their importance. These factors are captured in terms of numeric weights for edges between nodes in the associated graph to permit the system to assign display items to pages, and determine which pages should be linked, so that a user can move between pages in the most efficient manner. In a further embodiment, to accommodate limited display area that restricts the number of display items and page links that can be displayed simultaneously, the system can take into account multistage page moves that allow the user to access display items on different pages in sequence by moving from one page to another via links on other pages, through the use of "stepping-stone" nodes in the associated graph that record possible traversal routes in the document that are not represented in other formulations of the hypermedia-document-layout task.
    • 用于确定包含要在多个链接页面上布置的文本和图形的超媒体文档的结构的装置包括一个系统,其通过减少到图形划分来指定文本和图形到页面和页面之间的链接的分配,以及 使用图分割的优化技术。 在一个实施例中,显示项目和这些显示项目之间的关系以及其重要性的度量被列出。 这些因素是根据关联图中的节点之间的边缘的数字权重来获取的,以允许系统将显示项目分配给页面,并确定应链接哪些页面,以便用户可以以最有效的方式在页面之间移动。 在另一个实施例中,为了适应限制可同时显示的显示项目和页面链接的数量的有限显示区域,系统可以考虑允许用户通过移动来顺序地访问不同页面上的显示项目的多页面移动 通过使用关联图中的“踏脚石”节点来记录其他页面上的链接,从而在文档中记录可能的遍历路由,这些路径在超媒体文档布局任务的其他配方中未被表示。
