Presented here is a test from an extended system to cater for initially autostereo sequence datasets, although still suitable for all types of three-dimensional datasets. Extensions to do three-dimensional manipulation operations are defined that are both computationally efficient when applied to the coded form and are compression conscious in that they maintain compression performance. Autostereoscopic displays have been developed which create a three-dimensional image without the need for special glasses or headsets. They work by displaying multiple images each viewable over a very narrow field of view. This has the advantage of being able to look around objects. Increasing the number of images per view increases the bandwidth required. To aid stereo disparity in the human visual system the important features to retain in stereo sets are potentially different from standard two-dimensional images. Edge information and highlights have been shown to be of paramount importance for the human visual system to accurately perceive depth. The theme of coding three-dimensional regions as separate entities allows for a potential high compression ratio and subsequent transmission rate speed-up. A controlled merging scheme of regions is also presented which, being designed to keep all highlights and avoid defocusing of the image, gives a corresponding compression ratio increase while retaining the majority of the stereo cues.","PeriodicalId":132138,"journal":{"name":"Proceedings of Theory and Practice of Computer Graphics, 2003.","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131319486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we want to provide a technique that allows the simulation of up to 10,000 pedestrians walking in real-time. Simulation for such environments is difficult as a trade off needs to be found between realism and real-time simulation. This paper presents a pedestrian crowd simulation method aiming at improving the local and global reactions of the pedestrians. The method uses a subdivision of space into a 2D (two-dimensional) grid for pedestrian-to-pedestrian collision avoidance, while assigning goals to pedestrians to make their trajectories smoother and coherent. Goals are computed automatically and connected into a graph that reflects the structure of the city and triggers a spatial repartition of the density of pedestrians. In order to create realistic reactions when areas become crowded, local directions are stored and updated in real-time, allowing the apparition of pedestrian streams. Combining the different methods contributes to a more realistic model, while keeping a real-time frame rate for up to 10,000 simulated pedestrians.","PeriodicalId":132138,"journal":{"name":"Proceedings of Theory and Practice of Computer Graphics, 2003.","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125099436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
