Geometry Processing of 3D Objects and Applications (Lecture 29-06-2020 at 13:00 CET)

As per our schedule, the online monthly meeting will take place next Monday the 29th of June at 1pm CET. Mr Gerasimos Arvanitis from the Patras group will deliver a talk entitled “Geometry Processing of 3D Objects and Applications“. The abstract of the talk and a brief CV are given below.


New generation 3D scanning devices (e.g., conoscopic holography, structured light, photometric systems, etc.) have attracted a lot of attention due to their ability to provide reliable results. The easiness of capturing real 3D objects has created revolutionary trends in many areas (e.g., gaming, prominence of heritage, military, medicine, etc.) and has significantly increased the interest for static and dynamic 3D models. However, despite the technological evolution of the 3D acquisition devices, there are still limitations, deteriorating the quality of the generated results (e.g., noise, outliers, missing geometrical information due to partial observation and other abnormalities). These issues need to be addressed before the 3D models are used by other applications (such as segmentation, object recognition, tracking, etc.). Additionally, this digitized information is massive and raw, leading to the need for new essential and meaningful identification of features that will facilitate robust processing in various applications and feature-aware compression or simplification. These facts stress the need to focus on the development of computational models of visual attention, whose well-known outcomes are the saliency maps. Saliency maps are compact 3D representations, generated by simplifying, annotating, and/or changing the representation of a physical object/system giving more emphasis to geometrically meaningful parts. The salient features also typically satisfy important requirements such as scaling, rotation, resolution invariance. In this presentation, we will discuss methods and techniques that deal with the aforementioned research topics.

Short Bio

Gerasimos Arvanitis received the Diploma degree in Electrical and Computer Engineering and the M.Sc. degree in electronics and information processing from the University of Patras, Patras, Greece in 2009, and 2011, respectively. From 2011 to 2015, he worked as a software programmer at the Computer Technology Institute in Patras, Greece. He is currently pursuing his Ph.D. degree and he is a member of the Visualization and Virtual Reality Group at the University of Patras since January 2016. He has participated in 4 European projects and he acts as a regular reviewer for several technical journals and conferences. He has authored or co-authored over 25 papers in refereed journals, edited books, and international conferences. His main research interests include digital geometry processing, 3D modeling, reconstruction, compression, outliers removal, feature preserving denoising algorithms, and computer graphics.
