Wu, L. (author), Tiso, P. (author)Model order reduction techniques are widely applied in the floating frame of reference. The use of linear vibration modes, however, is not applicable when the elastic deformations become finite. In this paper, the non-linear elastic formulation, where the higher-order terms will be included in the strain energy expression to consider the bending...conference paper 2014

Wu, S.L. (author), Caviedes, J.E. (author), Karam, L. (author), Heynderickx, I.E.J.R. (author)Enhancement algorithms are typically applied to video content to increase their appeal to viewers. Such algorithms are readily available in the literature and are already widely applied in, for example, commercially available TVs. On the contrary, not much research has been done on enhancing stereoscopic 3D video content. In this paper, we...journal article 2014
