摘要： A technique for temporal smoothing of results from a scene analysis process which creates a sequence of visually pleasing and acceptable images generated in whole or part from such results. The technique applies temporal smoothing across time-related sets of scene analysis results. The spatial smoothing can be applied at various steps in the process: to images in the original sequence, to intermediate or final results of scene analysis in either a pixel-oriented or geometric domain, or to the images generated in whole or part from the scene analysis results. In a preferred embodiment, different levels of smoothing are applied to different parts of the intermediate or final results. The differentiation can be done using image masks (for pixel-oriented results) or geometry selection techniques (for geometric results). This allows a higher level of smoothing in certain areas where the generated visual images will benefit from such additional smoothing, while avoiding over-smoothing in other areas where the smoothing would obscure critical details within the generated images.
摘要翻译：一种用于从场景分析过程对结果进行时间平滑的技术，其创建从这样的结果全部或部分生成的视觉上令人满意的和可接受的图像序列。该技术对时间相关的场景分析结果集进行时间平滑。可以在该过程中的各个步骤中应用空间平滑：将原始序列中的图像，面向像素或几何域中的场景分析的中间或最终结果，或整个或部分从场景生成的图像分析结果。在优选实施例中，将不同级别的平滑应用于中间或最终结果的不同部分。可以使用图像掩模（用于像素取向的结果）或几何选择技术（用于几何结果）来进行区分。这允许在产生的视觉图像将受益于这种附加平滑的某些区域中更高水平的平滑，同时避免在平滑将模糊生成的图像内的关键细节的其他区域中的过度平滑。

摘要： A technique for converging upon a computer-based model of a real world or synthetic scene. The computer model makes use of abstraction-based data objects as well as image-based data objects. A correlation mesh provides links between related image-based and abstraction-based objects. An initial step in a process analyzes an input image stream and user inputs to derive initial image-based objects and abstraction-based objects for the scene model. Subsequent steps in the process allow user inputs to refine the image-based objects, abstraction-based objects and/or the correlation mesh. As a result, refinements to the image-based object model of the scene can improve the abstraction-based model of the scene, and refinements to the abstraction-based object model can improve the image-based model.
摘要翻译：一种用于融合现实世界或合成场景的基于计算机的模型的技术。计算机模型使用基于抽象的数据对象以及基于图像的数据对象。相关网格提供了相关的基于图像和基于抽象的对象之间的链接。过程中的初始步骤分析输入图像流和用户输入以导出用于场景模型的初始基于图像的对象和基于抽象的对象。该过程中的后续步骤允许用户输入来细化基于图像的对象，基于抽象的对象和/或相关网格。因此，对场景的基于图像的对象模型的改进可以改善场景的基于抽象的模型，并且基于抽象的对象模型的改进可以改进基于图像的模型。

摘要： A technique for displaying a visual representation of an estimated three-dimensional scene structure and the values of various parameters associated with the scene, together with a visual representation of at least one two-dimensional image used in the scene structure estimation algorithm. A user inputs information by adjusting parameters and/or specifying an element or region of the visual representations and supplies mark-ups and other information such as attributes for the element or region to be applied during a next iteration of the scene structure estimation algorithm. The scene structure estimation algorithm is then re-executed and the process repeats until the user is satisfied with the resulting visual scene structure.
