The 31st Conference on Graphics, Patterns and Images (SIBGRAPI 2018) is a leading annual event combining contributions from four major subjects related to image computing: computer graphics & vision, pattern recognition and image processing. SIBGRAPI comprises the main conference and several co-located workshops and short courses. With its high quality and low cost, it provides an exceptional value for students, academics and industry researchers. The proceedings have been published by IEEE Xplore since 1997.
This year SIBGRAPI will be held from October 29th to November 1st at the Bourbon Cataratas Convention & Spa Resort, in Foz do Iguaçu, Paraná, Brazil.
SIBGRAPI 2018 will be co-located with two other major events: SBGames 2018, the Symposium on Computer Games and Digital Entertainment, and SVR 2018, the Symposium on Virtual and Augmented Reality.
Title: Advances and Challenges in Live 3D Fingerprint Identification
Abstract:
Person identification using fingerprint impressions has been widely studied and employed for over 2000 years. Emerging 3D finger sensing technologies enable deformation free and hygienic acquisition of ground truth fingerprint information. Acquisition of subsurface 3D finger details can also enable detection of sophisticated presentation attacks and is critical for very high security applications. In addition to improving the user-friendliness and user-privacy, contactless 3D fingerprint identification also enables significantly enhanced limits on the individuality of fingerprints, which makes it very attractive for very large-scale personal identification applications. In this talk, we will discuss on recent advances towards such emerging 3D fingerprint identification technologies and share achieved results. I also plan to discuss on the technical challenges that are limiting the deployment of emerging contactless 3D fingerprint identification technologies and these needs to be addressed with much needed further research in this area.

Title: Multimodal Affective Computing for Clinical Research and Treatment.
Abstract:
What happens during psychotherapy that enables clients to improve? What affective mechanisms underlie depression? How does patient affect respond to novel biologically-based treatments? These are fundamental questions for clinical research and treatment.
Recent breakthroughs in automated multimodal analysis and synthesis make possible objective, valid, and efficient clinically useful behavioral indicators to address these and related questions. I will present: 1) human-observer and computational approaches to measurement that guide affective computing for clinical practice and research; 2) recent applications in depression and obsessive-compulsive disorder; 3) “expression transfer” that could enable sharing of clinical video without compromising patient anonymity; and 4) current challenges for affective computing in clinical practice and research.

His research has been supported by grants from the U.S. National Institutes of Health and U.S. National Science Foundation among other sponsors. He Chairs the Steering Committee of the IEEE International Conference on Automatic Face and Gesture Recognition (FG) and has served as General Chair of international conferences on automatic face and gesture recognition, affective computing, and multimodal interfaces.
Title: Additive Manufacturing (3D Printing): Challenges and opportunities for computer science.
Abstract:
The additive manufacturing (AM) technologies, also known as 3D Printing (3DP), appeared commercially in the 80’s decade as a solution for prototyping, mainly in the automobile industry. After three decades it is still considered in its infancy in terms of potential of development and new demands. AM is a disruptive new technology that permits to produce automatically any complex shape directly from a 3D model in a computer. This 3D model can be obtained from a myriad of sources ranging from a synthetic model in a computer-aided design (CAD) system to an anatomy obtained from a medical scanner and “printed“ as a touch-and-feel artifact in a couple of hours. This artifact can be produced in different materials and even in a multimaterial structure, only possible with AM technologies. Therefore its applicability and flexibility are limitless and very suitable for customized solutions. Materials science, engineering and computer science are pillars of AM, converging for an automated and stable process. AM is strongly impacting the aerospace and medical industry with big players entering the business. AM is also considered one of the enabling technologies of the Industry 4.0 (advanced manufacturing) opening huge opportunities for new research and developments aiming at automation and integration as a cyber-physical system (CPS) in the Industry 4.0 paradigm. Beyond the industry, advanced medical applications are on the way and needs for research and new solutions are growing together with applications. This is the case of a potential application of AM for production of human tissues and organs in the future where a bunch of developments is already demanded and new ones will certainly appear. This field, called biofabrication, promises to be a game-changer in the medicine for the next decades. The talk will highlight the “tip of the iceberg” in terms of challenges and opportunities driven by AM technologies from the computer science point of view in terms of research and developments that we expect for the next years. The talk will also highlight the AM applications in the CTI Renato Archer, mainly related to medical field like the open-source software InVesalius for medical image processing and integration with AM technologies that is being used in almost 150 countries. Finally, we expect to contribute to the computer science community with some topics fore research and innovations.
