Aims of the Workshop

The Workshop of Undergraduate Works (WUW/SIBGRAPI) aims to motivate discussions among undergraduate students and experts about research projects related to the topics covered by the SIBGRAPI (Conference on Graphics, Patterns and Images). 

All students currently enrolled in any undergraduate program (or graduated in the last 12 months) who are engaged in the research topics covered by SIBGRAPI are strongly invited to submit their works.

Paper Submission

Submitted papers can be written in Portuguese, English or Spanish. However, submission in English is strongly encouraged since the workshop proceedings containing the accepted papers will be published in the SIBGRAPI Electronic Proceedings (with ISSN). Moreover, only papers written in English will be eligible for being evaluated by the Technical Program Committee who will award the best papers of the workshop. Participants should also explicitly mention previous publications by the authors (if there are any) in their WUW submissions, especially those interested in becoming more competitive for receiving an award. The acceptance of a paper implies that at least one of its authors will register for the workshop to present it. The research article can be written by an individual student or by a team of students, however, in both cases, should have an advisor as one of the co-authors responsible for the research.


The Review Process 

Each submitted paper will be reviewed by three referees, based on its originality, relevance, technical soundness and clarity of presentation. Papers must be no longer than 6 pages, including all figures and references. All submissions must be in Adobe Portable Document Format (PDF) and must comply with the IEEE 2-column SIBGRAPI 2013 conference format for full papers (which is available here), with the following adjustments: the author's names should not be omitted, disregarding the requirement of anonymity for the articles. In particular, students must appear as the first authors and the advisor as the last author, with eventual co-advisors and other collaborators in the middle. Texts in Portuguese and Spanish should also include, after the abstract in Portuguese/Spanish, an abstract written in English. Papers should be submitted electronically through JEMS system.


Best Paper Selection

Awards will be given for the three best papers, presented at the WUW workshop by one of the author students. Awarded authors will receive a certificate, as well as a special recommendation for publication at an electronic journal.


Posters Preparation

Posters 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 2013 poster template in PowerPoint or Corel Draw formats.
