During the last years, Convolutional Neural Networks (CNNs) have achieved state-of-the-art performance in image classification. Their architectures have largely drawn inspiration by models of the primate visual system. However, while recent research results of neuroscience prove the existence of non-linear operations in the response of complex visual cells, little effort has been devoted to extend...
Tele-immersion (TI) related technologies can change the way people interact and bridge the gap between the physical and digital worlds. However, while the technology itself advances, most developed platforms have complex setups and require large investments. In this work, a low-cost platform is introduced, integrating multiple TI-related advances. Focusing on ease of use and rapid deployment, a fast...
In this work, we explore the potential of exploiting activity-related global features in order to improve the performance of an existing human Time-Varying Mesh (TVM) compression scheme. The TVM compression scheme used, employs two kinds of frames, namely Intra(I)-Fames and Enhanced Predicted(EP) Frames. In this scheme, I-Frames are used as a reference to encode EP-Frames. The paper introduces a strategy...
In this paper, a novel skeleton-based approach to human time-varying mesh (H-TVM) compression is presented. The topic of TVM compression is new and has many challenges, such as handling the lack of obvious mapping of vertices across frames and handling the variable connectivity across frames, while maintaining efficiency, which are the most important ones. Very few works exist in the literature, while...
Hereby, a new publicly available 3D reconstruction-oriented dataset is presented. It consists of multi-view range scans of small-sized objects using a turntable. Range scans were captured using a Microsoft Kinect sensor, as well as an accurate laser scanner (Vivid VI-700 Non-contact 3D Digitizer), whose reconstructions can serve as ground-truth data. The construction of this dataset was motivated...
