We study algorithmic aspects in the management of geometric scenes in interactive walkthrough animations. We consider arbitrarily large scenes consisting of unit size balls. For a smooth navigation in the scene we have to fullll hard real time requirements. Therefore, we need algorithms whose running time is independent of the total number of objects in the scene and that use as small space as ...

An augmented reality (AR)-based guidance system for use in indoor artistic-statue exhibitions is proposed to guide a visitor to find and appreciate statue artworks. For statue recognition, a skillful method of exhaustive matching of statue-image features is proposed, which “learns” each statue by capturing its images from different directions to construct a database, and recognizing each statue...

Knowing website traffic flow and structure is essential in order to make website successful and better target visitors. In this article website traffic and structure analysis models in combination of intelligent methods are proposed and theoretical predictions are made on how and what factor changes in website structure will affect visitor click paths and overall website activity.

Visitor use surveys and water quality data indicates that high visitor use levels of two rivers in Puerto Rico does not appear to adversely affect several water quality parameters. Optimum visitor use to maximize visitor defined satisfaction is a more constraining limit on visitor use than water quality. Our multiple regression analysis suggests that visitor use of about 150 visitors per day yi...
