Dynamic Texture Modelling and Editing Using Temporal Mixing Coefficients Reduction
 Havlíček, Michal
Real world materials often change their appearance over time. If these variations are spatially and temporally homogeneous then the visual appearance can be represented by a dynamic texture which is a natural extension of classic texture concept including the time as an extra dimension. In this article we present possible way to handle multispectral dynamic textures based on a combination of input data eigen analysis and subsequent processing of temporal mixing coefficients. The proposed method exhibits overall good performance, offers extremely fast synthesis which is not restricted in temporal dimension and simultaneously enables to compress significantly the original data and additionally perform texture editing.

Dynamic Textures Modelling with Temporal Mixing Coefficients Approximation
 Havlíček, Michal
Appearance of many real world materials is not static but changes in time. In case of spatially and temporally homogeneous changes the material can be represented by means of dynamic texture. Dynamic texture modelling is a challenging problem. In this article we present possible solution based on eigen analysis of input data and subsequent processing and modelling of temporal interpolation eigen coefficients using a combination of piecewise linear approximation and normal distribution sampling. The proposed method shows good performance, enables compress significantly the original data and extremely fast synthesis of arbitrarily long extension of the original texture.
