Call for Technical Paper Contributions Original unpublished papers are invited. All manuscripts submitted to SIBGRAPI 2015 Technical Paper Track must be in English and should be between 6 and 8 pages to be prepared following the submission instructions below. Scope: Original contributions to the following research areas are solicited: Computer graphics Computer vision Image processing Pattern recognition Important Dates: Full Paper Submission: April 10, 2015 Notification of Acceptance: May 18, 2015 Camera ready due: June 05, 2015 SIBGRAPI 2015 submission deadline is hard. No extensions will happen. Submission Guidelines: All full papers are to be double blindly reviewed by at least three experts in the work topic. All papers recommended by the reviewers will be accepted. The final program will only include papers with at least one author registered in the conference. All papers included in the proceedings of the conference are submitted to IEEE Xplore, and scheduled for oral or poster presentation. Authors of the best papers will be invited to submit an extended version of their work to a journal. Submission Instructions: The SIBGRAPI IEEE LaTeX style is available here. Please follow the included instructions and the IEEE formatting guidelines, avoiding any change to the format (in particular avoiding \\vspace command, or creating subsections or paragraph title with any command different from \\subsection or \\paragraph). The bibliography should be formatted with a 9pt font. Please do not change the font size, even if it helps to comply with the page limit! The paper length may vary depending on the track you are submitting the paper. Please check the respective calls for the maximum allowed number of pages for each track. The illustrations of the paper should be generated either truly vectorial or rasterized with at least 300dpi. Paper submission will be handled via CMT system. Oral presentation: The oral presentations must fit in 20 minutes, with additional 5 minutes for questions. Slides should be prepared in English. Authors may use the SIBGRAPI 2015 oral presentation template (available soon). Poster presentation Posters should be prepared using an area of 90cm x 120 cm at maximum and in a portrait orientation. The use of small font size is not recommended. There is no need to submit the poster in the submission system. Authors may follow the SIBGRAPI 2015 poster template (available soon). Anonymity Requirements Once the review process of submissions will be double blind, authors must prepare their manuscripts without including any indication of their identities or institutional affiliations. Author\'s identities will be tracked only by the submission system, and visible only by the track chairs. The program committee members and referees who review the paper will not know the identity of the authors. To ensure anonymity of authorship, authors must prepare their manuscript as follows: Authors\' names and affiliations must not appear on the title page or elsewhere in the paper. Instead, please include under the title the number assigned to your paper by the on-line paper registration system, for instance, by including the command \\author{Paper id: Manuscript number} in your LaTeX source file. Funding sources must not be acknowledged anywhere in the paper. Research group members or other colleagues or collaborators must not be acknowledged anywhere in the paper. It is strongly suggested that the submitted file is named with the assigned submission number. For example, if your assigned paper number is 39352, then name your submitted file 39352.pdf. Source file naming must also be done with care. For example, if your name is Jane Smith and you submit a PDF file generated from a .dvi file called Jane-Smith.dvi, one can infer your authorship by looking into the PDF file. The same rules apply to supplementary material. You must also use care in referring to related past work, particularly your own. For example, avoid mention to your work as \"In our previous work [1,2]...\", prefer third person referencing as \"In previous work [1,2]...\". Despite the anonymity requirements, you should still include all relevant work of your own in the references, using the above style (omitting them could potentially reveal your identity by negation). It is the responsibility of authors to do their best to preserve anonymity. Papers that do not follow the guidelines here, or otherwise potentially reveal the identity of the authors, are subject to immediate rejection.
