摘要

将解释性VRML建模与实时视频相关联的经验表明，它是解释视频图像内容的有效技术。然而，搜索VRML模型需要用户进行交互式探索。如果在数据库中运行搜索以返回图像中一个或多个对象的位置，则观看者很难快速识别视频图像中感兴趣的对象的位置。有人建议，在许多情况下，通过扭曲逼真的照片建模场景来吸引人们对特定部分的注意是有用的，从考古演示或规划建议中的不确定性的表现，到确定视频剪辑或实时视频帧中感兴趣的对象的位置。讨论了几种可能的方法的优缺点。

Pointing the finger; a role for hybrid representations in VR and video?

Experience gained in associating interpretative VRML modelling with real-time video has demonstrated that it is an effective technique for explaining the content of the video image. However searching the VRML model requires interactive exploration by the user. It is more difficult for the viewer to quickly identify the location of an object of interest in the video image, if a search is run in the database to return the location of an object or objects in the image. It is suggested that there are a number of instances where it would be useful to distort a photo realistic modelled scene to draw attention to specific-portions, ranging from the representation of uncertainty in archaeological presentations or planning proposals, to the identification of the location of an object of interest in a video clip or live video frame. The advantages and disadvantages of some possible approaches are discussed.
