Although commercial and open-source software exist to reconstruct a static object from a sequence recorded with an RGB-D sensor, there is a lack of tools that build rigged models of articulated objects that deform realistically and can be used for tracking or animation. In this work, we fill this gap and propose a method that creates a fully rigged model of an articulated object from depth data...

In this paper we present parallel 2D and 3D finite element computation of unsteady, incompressible free-surface flows. The computations are based on the DeformableSpatial-Domain/Stabilized Space-Time (DSD/SST) finite element formulation, which takes automatically into account the motion of the free surface. The free-surface height is governed by a kinematic free-surface condition, which is also...

Two-dimensional mesh-based models provide a good alternative to motion estimation and compensation. The estimation of the best motion vectors at the node-point motion vectors is a challenging task. To this effect, Nakaya et al. proposed a hexagonal matching procedure. Toklu et al. improved the hexagonal search algorithm in terms of both motion estimation accuracy and computational complexity by...

Usually object segmentation and motion estimation are considered (and modelled) as different tasks. For motion estimation this leads to problems arising especially at the boundary of an object moving in front of another if e.g. prior assumptions about continuity of the motion field are made. Thus we expect that a good segmentation will improve the motion estimation and vice versa. To demonstrat...

This paper presents a generic-model based human-body modeling method which take the anatomical structure of the human body into account. The generic model contains anatomical structure of bones and muscles of the human body. For a given target skin mesh, the generic model can be scaled according to the skin, and then morphed to be fitted to the shape of the target skin mesh. After an anchoring ...

We study the thermal motion of colloidal tracer particles in entangled actin filament (F-actin) networks, where the particle radius is comparable to the mesh size of the F-actin network. In this regime, the ensemble-averaged mean-squared displacement of the particles is proportional to tau(gamma), where 0<gamma<1 from 0.1<tau<100 s and depends only on the ratio of the probe radius to mesh size....

The proposed technique is designed for interpolating video frames often dropped during compression using standards, such as MPEG-4 and H.263 at very low bit rates. The coarse motion vector field is refined at the receiving side using mesh-based motion estimation instead of using computationally intensive dense motion estimation. We propose a framework for detecting and utilizing local motion bo...

This article presents an analysis-synthesis scheme using 2D deformable meshes for video coding. The analysis stage allows to decouple the motion from the texture and to code each information independently. The motion is represented by a 2D deformable mesh which provides long term tracking of the texture. The texture frames are extracted by motion-compensating the frames on a reference grid and ...
