Call for Contributions for the Technical Papers Track
The technical papers track of SIBGRAPI 2012 welcomes submissions describing research, practice, experience and applications in all areas of Computer Graphics, Computer Vision, Image Processing, and Pattern Recognition, including but not limited to the following topics: Animation and simulation, Biomedical imaging and visualization, Biometrics, Computational geometry, Computer vision and robotics, Document processing and analysis, Feature extraction and matching, Games, Geometric and solid modeling, Graphical interfaces, Graphics hardware, Image and video analysis, filtering and restoration, Image and video registration, retrieval and segmentation, Information visualization, Visual learning, Mathematical morphology, Mobile graphics, Motion and tracking, Non-photorealistic rendering, Pattern recognition, Point-based modeling, Real-time imaging and rendering, Remote sensing and geophysical imaging, Scientific visualization, Shape representation and matching, Simplification and compression, Stereo/3D imaging, Surface reconstruction, Virtual and augmented reality and Visual data mining.

The paper length should not exceed 8 pages (IEEE format). All full papers are double blindly reviewed by at least three experts in the topic of the work, and all papers recommended by the reviewers will be accepted. All accepted papers are published in the proceedings of the conference (available at 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:

    Image and Vision Computing (2003)
    Pattern Analysis and Applications (2004)
    Computerized Medical Imaging and Graphics (2004)
    Journal of Mathematical Imaging and Vision (2006)
    Pattern Recognition Letters (2007, 2008)
    Computers & Graphics (2007)
    Computer Graphics Forum (2007, 2009)
    International Journal of Pattern Recognition and Artificial Intelligence (2010)
    The Visual Computer (2010)

Important Dates

    Submission Deadline: May 4th, 2012
    Notification of Acceptance: June 17th, 2012
    Camera Ready: July 6th, 2012

Best Paper Selection
The 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 instruction
The 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 Presentation
Each accepted paper will be presented orally or in poster form during the event. The oral presentations must fit in 25 minutes, with additional 5 minutes for questions. The authors will be invited to choose the type of presentation.
