On behalf of the SIBGRAPI 2017 Organizing Committee, we would like to welcome you to the 30th SIBGRAPI - Conference on Graphics, Patterns and Images, in Niterói, Brazil.
SIBGRAPI 2017 is promoted by the Brazilian Computer Society (SBC). It is held in-cooperation with ACM SIGGRAPH and received financial sponsorship from CAPES, CNPq, FAPERJ, PROPPi UFF, NVIDIA, IBM, and globo.com. Over the past three decades, SIBGRAPI has become a premium forum for researchers, practitioners, and students to share, learn, and advance the state-of-the-art in the areas of computer graphics, visualization, computer vision, image processing, and pattern recognition.
This is the first edition of SIBGRAPI being held in Niterói, a municipality of the state of Rio de Janeiro in the southeast region of Brazil. The city lies across Guanabara Bay facing the city of Rio de Janeiro and forms part of the Rio de Janeiro Metropolitan Area. The word "Niterói" comes from the Tupi language and means "water that hides". It was founded on November 22, 1573, by the Tupi Amerindian chief Araribóia. It makes Niteroi the only Brazilian city to have been founded by a non-Christian, non-assimilated Brazilian Amerindian. The Niterói Contemporary Art Museum (MAC), the city's main landmark, was designed by the famous Brazilian modernist architect Oscar Niemeyer. This remarkable architectural masterpiece will be the scenario of the conference dinner.
The conference venue, the Instituto de Computação of the Universidade Federal Fluminense (IC-UFF), is located in a privileged area of Niterói, within walking distance of the conference's hotel, restaurants, and the Niterói Contemporary Art Museum.
We would like to take this opportunity to thank all the volunteers, invited speakers, program chairs, tutorial chairs, workshop chairs, authors, sponsors, and participants for their contributions that help make SIBGRAPI 2017 successful!
Welcome to Niterói and enjoy SIBGRAPI 2017!

SIBGRAPI 2017 - The Conference on Graphics, Patterns and Images, is an international venue annually promoted by the Brazilian Computer Society (SBC). The proceedings of the event have been published by IEEE Computer Society Press since 1997. In addition, SIBGRAPI 2017 includes two pre-conference events whose proceedings are published as Special Sections of Elsevier's Computers & Graphics Journal and of the IEEE's Geoscience and Remote Sensing Letters, and a post-conference publication as a Special Issue of Elsevier's Journal of Visual Communication and Image Representation.
The 30th edition of SIBGRAPI is being jointly organized by the Instituto de Computação of the Universidade Federal Fluminense (IC-UFF), the Programa de Engenharia de Sistemas e Computação of the Universidade Federal do Rio de Janeiro (PESC-COPPE-UFRJ), and by the Departamento de Informática of the Pontifícia Universidade Católica do Rio de Janeiro (DI, PUC-Rio). It will be held in Niterói-RJ from October 17 to 20, 2017. SIBGRAPI 2017 was a unique opportunity for participants to attend the technical sessions, the mini courses, the workshops and the four keynotes, while enjoying the beautiful view of Guanabara Bay.
This year, SIBGRAPI featured a particularly rich technical program including 60 accepted full papers published in the conference proceedings (by IEEE CS Press), 9 full papers published in a Special Section of Elsevier's Computers & Graphics Journal, and 7 full papers published in a Special Stream of the IEEE's Geoscience and Remote Sensing Letters journal.
Each paper received three or more reviews from members of the Program Committee to ensure high standards of quality. Those published on the conference proceedings underwent a one-stage double blind review process, while the ones published in the Special Section of the Elsevier's Computers & Graphics Journal and IEEE's Geoscience and Remote Sensing Letters underwent a three-stage double-blind review process.
From the 75 papers presented at the conference, 52 were delivered as oral communications and 23 as posters (due to time constraints) grouped into 12 thematic sessions.
Five outstanding keynote speakers further enriched the SIBGRAPI 2017 program:
In addition, SIBGRAPI 2017 will also host the following events:

Tutorials of SIBGRAPI 2017 received proposals in Computer Vision (CV) and Pattern Recognition (PR). All tutorials were blindly reviewed by at least two experts in the topic and judged by some criteria as: relevance for the conference, expected size of the audience, potential to attract participants to the conference, originality and qualification of the instructors in the topic of the tutorial.
The four accepted tutorials are going to be presented in the first day of the conference, held in Niterói, Rio de Janeiro, Brazil, and will be free of charge to all conference attendees. In addition, the authors of the selected tutorials prepared a survey paper in English, in the tutorial's topic, and submitted to the IEEE Xplore Digital Library after being peer reviewed.
We would like to thank all authors and the reviewers for the great work and wish a very productive day to all attendees!

The Workshop of Theses and Dissertations (WTD) is a venue for publishing six-page condensed papers of theses and dissertations concluded in the last year. The workshop aims to advertise the works and also motivate discussions around the graduate-level research related to the topics covered by SIBGRAPI.
Accepted works, written either in Portuguese or English, are included in the electronic proceedings and presented in a poster session. This year, we received 17 submissions. Each paper has been evaluated by two different reviewers and, in the end, disregarding the withdrawn papers, a total of 14 works have been accepted.
We would like to thank the authors for their contribution, and the reviewers for their effort and dedication. We would like also to congratulate the local organizing committee and the program committee for their hard work to make this event possible.

The main goals of the Workshop of Undergraduate Works (WUW) are to motivate undergraduate students involved in research projects on Computer Graphics, Image Processing and Computer Vision to attend the SIBGRAPI conference, and to provide opportunities and environment for these students to present and discuss their research among themselves and with experts in the area. Accepted works are included in the electronic proceedings, formatted in four-page papers and written either in Portuguese or in English. This year, the three best works presented at the WUW poster session will receive a best-paper award and a special recommendation for publication at Revista Eletrônica de Iniciação Científica (REIC).
This year, we accepted 19 out of 21 submissions for poster presentation during the SIGBRAPI-WUW. In the review phase, each paper was evaluated by at least two reviewers.
We would like to thank the authors for their contributions, and the reviewers, who dedicated their valuable time to evaluate the submitted papers. Finally, we would like to congratulate the local organizing committee and the program committee for their excellent work in leading the SIBGRAPI activities.
