All accepted papers are published in the proceedings of the conference (submitted to IEEE Xplore) and scheduled for oral or poster presentation. From 1997 to 2008, SIBGRAPI proceedings were published by IEEE Computer Science, by CPS since then, and since 1996, at the SIBGRAPI Digital Library Archive, maintained by Instituto Nacional de Pesquisas Espaciais (INPE). As in previous SIBGRAPI editions, the authors of the best papers will be invited to submit extended versions of their work to highly ranked international journals in the respective fields. In particular, extended versions of the best papers of previous SIBGRAPI were published in special issues of:
Important Dates
Best Paper SelectionThe best paper and best student paper will be awarded during the event based on the reviewers' judgment and the quality of the presentation. Moreover, as in previous SIBGRAPI editions, the authors of the best papers will be invited to submit extended versions of their work to highly ranked international journals in the respective fields. In particular, in previous editions, the best computer graphics papers have been published in Computer Graphics Forum and The Visual Computer Journal. This year, the best papers on Computer Graphics related topics will be invited to submit an extended version to be considered for publication in Computer Graphics Forum. The best papers in Image Processing, Computer Vision and Pattern Recognition will be invited to submit an extended version to be reviewed for publication in a special issue of Pattern Recognition Letters.Author's instructionThe papers must be written in English, formatted according to the IEEE standard. They should not exceed 8 pages, including bibliography and illustrations, and should not contain any information that could identify the author in the submission phase. Works on the same topic may be submitted to other tracks of the event, in particular when related to student work. Further instructions are available at the submission instructions' page.Oral or Poster PresentationEach accepted paper will be presented orally or in poster form during the event. The oral presentations must fit in 20 minutes, with additional 5 minutes for questions. The authors will be invited to choose the type of presentation.Posters PreparationPosters should be prepared using an area of 90cm x 120 cm at maximum and in a portrait orientation. The use of small fonts on the text production is not recommended. It is not necessary to include the poster in the JEMS system. The authors may follow the SIBGRAPI 2012 poster template in PowerPoint or Corel Draw formats).Oral Presentation Slides TemplateA template for oral presentations using SIBGRAPI 2012's arts is available here.Chairs
