Traditional animation's flexibility in terms of choice of appearance and style is appealing but in certain aspects it is very time consuming. There is therefore a need to develop techniques that exploit the speed of computer animation but provide the variety of styles of traditional animation. This paper attempts to simulate hand drawn cartoon animation styling while incorporating traditional exaggerated cartoon movement.","PeriodicalId":226195,"journal":{"name":"Proceedings 20th Eurographics UK Conference","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130925706","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}

With advances in videoconferencing software and the move towards a broadband Britain, a new opportunity has arisen for distributed learning to take place whilst retaining synchronous contact with a tutor. De Montfort University's REal time Access to Learning IT (REALITY) is remote, real-time, computer based training in computer applications. It uses a combination of desktop videoconferencing and application sharing to provide remote, distributed, learners with live tuition. The target audience for REALITY are people who, for whatever reason, cannot readily access traditional learning establishments but for whom distance learning is not an option either. The aim is to provide training facilities at a variety of times and locations which are local and familiar and which avoid the potentially negative connotations of traditional educational institutions. With funding from BT, the initial phases of the project are now complete and have been evaluated. The findings indicate that despite technical difficulties and the strain of working at a distance using unfamiliar technology, most of the participants responded favourably to their REALITY experiences.","PeriodicalId":226195,"journal":{"name":"Proceedings 20th Eurographics UK Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123394354","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}

Motions are locally modified using perceptual cues extracted from the music. The key to this approach is the use of standard music analysis techniques on complementary MIDI and audio representations of the same soundtrack. These musical features then guide the motion editing process. It allows users to easily combine different aspects of the music with different aspects of the motion.","PeriodicalId":226195,"journal":{"name":"Proceedings 20th Eurographics UK Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132369429","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}

The exponential growth of digital media on both the WWW (Reddy and Fletcher, 1998) and home imaging equipment has prompted the development of faster, more accurate indexing algorithms. Successful techniques have the ability to summarise the features of an image into a relatively small key. We present a technique that uses the features of a genetic algorithm to quantize the content of an image directly in the DCT domain. The benefits of working in this domain, apart from the substantial savings of avoiding image reconstruction, is that the coefficients provide spatial information in a form well suited for image indexing.","PeriodicalId":226195,"journal":{"name":"Proceedings 20th Eurographics UK Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129680287","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}

When interpolating projected texture maps, regions of texture incongruence can generate artefacts. Non congruent texture regions are the result of unmodelled features in the geometric scene model. We show how a perception based metric can be used to control the interpolation process and reduce these artefacts. The metric, based upon the human perception of Mach bands, is also used to evaluate the new interpolation method against current techniques.","PeriodicalId":226195,"journal":{"name":"Proceedings 20th Eurographics UK Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121506498","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}

Our method requires no user interaction, and makes use of image salience and gradient information to determine the implicit ordering and attributes of individual brush strokes. The benefits of our technique are complete automation, and mitigation against the loss of image detail during painting. Strokes from lower salience regions of the image do not encroach upon higher salience regions; this can occur with some existing painting methods. We describe our algorithm in detail, and illustrate its application with a gallery of images.","PeriodicalId":226195,"journal":{"name":"Proceedings 20th Eurographics UK Conference","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131462323","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}
