From the earthen figures of ancient times to mechanical dolls, teddy bears and robots, is it not true that man has conceived such objects in his imagination, then formed attachments and transferred emotions to them? In this paper, we address the issues of communication and esthetics of artificial life that possess this \"human form\" in modern society, both from artistic and engineering standpoints. An example is presented in which emotions are interpreted from human voices and emotional responses are triggered within the interactive setting of \"MIC & MUSE\". MIC is a cute male child who is an emotion communication character. MUSE is a goddess; she has the capability of musical communication.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131351047","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}

{"title":"Burst handling of digital video traffic","authors":"T. Chiueh, L.-C. Chang","doi":"10.1109/MMCS.1996.535021","DOIUrl":"https://doi.org/10.1109/MMCS.1996.535021","url":null,"abstract":"Digital video traffic is inherently bursty for two reasons: the inherent motion of the objects and cameras, and artifacts of the compression algorithms. Because digital video playback requires bandwidth guarantees from the underlying I/O and network systems, the bursty nature of video traffic forces bandwidth reservations to be made at the level of the peak data rates rather than at the average data rates. This paper addresses the burstiness problem in digital video traffic by proposing changes to the MPEG compression/decompression algorithm. The resulting algorithm, called block-by-block (BBB) difference coding, successfully minimizes the difference between peak and average bit rates by a factor of 2 to 3 on average, without compromising the compression efficiency, coding speed and video quality.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114696302","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}

For the first issue, we propose a semi-static resource reservation scheme, which attempts to utilize resources efficiently and maximize the number of clients being serviced concurrently. For the second issue, we propose a server-initiated flow control scheme, in which the traffic flow is controlled by the server alone, using historical video information; thus, no feedback messages from its downstream switches are needed. Our approach is evaluated under a wide range of parameters through extensive simulations driven by trace data from various MPEG video streams.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131525933","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 the sensing system, a scene is observed by using a camera matrix. An excellent stereo algorithm SEA which utilizes 3/spl times/3 image matrix recovers the depth information of the scene with the density and the sharpness required for high quality image generation. In the display system, following the viewing position of the observer, 2D images with proper notion parallax are generated and presented. A novel algorithm to determine the view parameters suitable for reproducing the motion parallax on a fixed screen and an image generation algorithm which can cope with arbitrary viewing positions are described. A prototype system has been developed to demonstrate the feasibility of the proposed algorithms.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123186362","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}

We examine the impacts that VCR functions have on the smoothed delivery of stored video. We introduce the notion of VCR window, which allows users to have full VCR functionality in a limited window while not requiring increases in the bandwidth reservations. In addition, we introduce a resource reservation scheme that can be used with the VCR window for the delivery of stored video. To test the applicability of the VCR window in video on demand systems, we have digitized 15 full length movies for experimental data. Our results indicate that time limited VCR functionality can be provided while retaining a fairly high network utilization.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124377943","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}

We have applied this approach to in-situ electron microscopy experiments that require dynamic interaction with the specimen under observation, as it is excited with external stimuli, i.e., temperature variation, EM field variation etc. The dynamic operations include control of the sample's position and orientation under the electron beam, the illumination conditions and focus, etc. Remote control via wide area networks like the Internet that do not offer real time data and command delivery guarantees is not practical for the finely tuned adjustments that dynamic studies require. We suggest that an effective approach to remote operation for this class of dynamic control applications must involve automated control operations performed near the instrument in order to eliminate the wide area network real-time delivery requirement. Our approach to this problem is based on advanced computer vision algorithms that permit instrumentation adjustments to be made in response to information extracted from the video signal generated by the microscope imaging system. We have determined the type of servo loops needed to enable remote operation and collaboration, and have introduced a novel partitioning of the control architecture for implementing this approach.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115851672","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}
