A Lattice-based Mrf Model for Dynamic Near-regular Texture Tracking and Manipulation
ANear-regular texture (NRT) is a geometric and photometric deformation from its regular origin – a congruent wallpaper pattern formed by 2D translations of a single tile. A dynamic NRT is an NRT under motion. Correspondingly, the basic unit of a dynamic NRT is a well-defined texton, as a geometrically and photometrically deformed tile, moving through a 3D spatiotemporal space. Although NRTs are...
متن کاملTracking Dynamic Near-Regular Texture Under Occlusion and Rapid Movements
We present a dynamic near-regular texture (NRT) tracking algorithm nested in a lattice-based Markov-Random-Field (MRF) model of a 3D spatiotemporal space. One basic observation used in our work is that the lattice structure of a dynamic NRT remains invariant despite its drastic geometry or appearance variations. On the other hand, dynamic NRT imposes special computational challenges to the stat...
متن کاملA dynamic lattice model for heterogeneous materials
In this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. The Timoshenko beam theory is applied instead of the classical Euler-Bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. T...

متن کاملNear-Regular Texture Synthesis
This paper describes a method for seamless enlargement or editing of difficult colour textures containing simultaneously both regular periodic and stochastic components. Such textures cannot be successfully modelled using neither simple tiling nor using purely stochastic models. However these textures are often required for realistic appearance visualisation of many man-made environments and fo...
