    3D Mesh Description Using ''Subdivided Shape-Curvature-Graphs''
    (The Eurographics Association, 2019) Beguet, Florian; Guise, Jacques De; Schmittbuhl, Matthieu; Mari, Jean-Luc; Cresson, Thierry; Fusiello, Andrea and Bimber, Oliver
    This paper presents a shape descriptor for 3D meshes using a graph to represent a polyhedral mesh which is then used to extract patterns from the shape. The use of Subdivided Shape-Curvature-Graphs makes it possible to not only recognize the similarities of mesh details but also determine the self-similarity of local portions of the object by adding topological information to the graph. The proposed method divides the mesh into 8 categories of patches using the discrete curvatures. These patches are cleaned; afterwards, to add topological information, a new "segmentation" patch is added. Finally, an approach is developed to extract and compare the subgraphs and thus be able to obtain the self-similarity of local parts of the mesh.

    Enhanced Reconstruction of Architectural Wall Surfaces for 3D Building Models
    (The Eurographics Association, 2019) Michailidis, Georgios-Tsampikos; Pajarola, Renato; Fusiello, Andrea and Bimber, Oliver
    The reconstruction of architectural structures from 3D building models is a challenging task and a lot of research has been done in recent years. However, most of this work is focused mainly on reconstructing accurately the architectural shape of interiors rather than the fine architectural details, such as the wall elements (e.g. windows and doors). We focus specifically on this problem and propose a method that extends current solutions to reconstruct accurately severely occluded wall surfaces.

    Flexible Type: Methods and Applications of Modifying Glyph's Horizontal and Vertical Weight
    (The Eurographics Association, 2019) Kumawat, Nirmal; dhanuka, praveen kumar; Fusiello, Andrea and Bimber, Oliver
    Graphic designers create logos or artworks by using various tools such as Adobe Illustrator, InDesign etc. Many times, designers face a major problem where they want to change the visual appearance of the text to fit the design in the current context or to make the design look better, but text editing options provided today are very limiting to the user's creativity. The designers get around this by converting text to outlines and then modifying each glyph like a separate graphic. This leads to text no longer being live (essentially unlinked) and the edits for each glyph can be time consuming. The poster presents methods for modifying glyph's horizontal and vertical weight. Later, the poster aims to provide the application of such modification to generate multiple styles by modifying glyph's overall Weight, Width, CapHeight, xHeight, height of Ascender and Descender etc.

    Visual-auditory Representation and Analysis of Molecular Scalar Fields
    (The Eurographics Association, 2019) Malikova, Evgeniya; Adzhiev, Valery; Fryazinov, Oleg; Pasko, Alexander; Fusiello, Andrea and Bimber, Oliver
    The work deals with a visual-auditory representation and an analysis of static and dynamic continuous scalar fields.We propose a general approach and give examples of dynamic and static objects representations related to molecular data simulations. We describe the practical application and demonstrate how the approach may help to track geometrical features.

    VITON-GAN: Virtual Try-on Image Generator Trained with Adversarial Loss
    (The Eurographics Association, 2019) Honda, Shion; Fusiello, Andrea and Bimber, Oliver
    Generating a virtual try-on image from in-shop clothing images and a model person's snapshot is a challenging task because the human body and clothes have high flexibility in their shapes. In this paper, we develop a Virtual Try-on Generative Adversarial Network (VITON-GAN), that generates virtual try-on images using images of in-shop clothing and a model person. This method enhances the quality of the generated image when occlusion is present in a model person's image (e.g., arms crossed in front of the clothes) by adding an adversarial mechanism in the training pipeline.

    Voxelizing Light-Field Recordings
    (The Eurographics Association, 2019) Schedl, David; Kurmi, Indrajit; Bimber, Oliver; Fusiello, Andrea and Bimber, Oliver
    Light fields are an emerging image-based technique that support free viewpoint navigation of recorded scenes as demanded in several recent applications (e.g., Virtual Reality). Pure image-based representations, however quickly become inefficient, as a large number of images are required to be captured, stored, and processed. Geometric scene representations require less storage and are more efficient to render. Geometry reconstruction, however, is unreliable and might fail for complex scene parts. Furthermore, view-dependent effects that are preserved with light fields are lost in pure geometry-based techniques. Therefore, we propose a hybrid representation and rendering scheme for recorded dense light fields: we extract isotropic scene regions and represent them by voxels, while the remaining areas are represented as sparse light field. In comparison to dense light fields, storage demands are reduced while visual quality is sustained.
