چکیده

We address the problem of modeling the spatial and temporal second-order statistics of video sequences that exhibit both spatial and temporal regularity, intended in a statistical sense. We model such sequences as dynamic multiscale autoregressive models, and introduce an efficient algorithm to learn the model parameters. We then show how the model can be used to synthesize novel sequences that extend the original ones in both space and time, and illustrate the power, and limitations, of the models we propose with a number of real image sequences.

Parametric Texture Model based on Joint Statistics

Texture images are a special class of images that are spatially homogeneous and consist of repeated elements, often subject some randomization in their location, size, color, orientation, etc. Textures can be classified into different classes or groups based on their structure and origin. Figure 1 gives some example textures. Textures are widely used in varied fields ranging from bio medical im...

Gibbs Fields with Multiple Pairwise Pixel Interactions for Texture Simulation and Segmentation

Modelling of spatially homogeneous and piecewise-homogeneous image textures by novel Markov and non-Markov Gibbs random fields with multiple pairwise pixel interactions is briefly overviewed. These models allow for learning both the structure and strengths (Gibbs potentials) of the interactions from a given training sample. The learning is based on first analytic and then stochastic approximati...

Pairwise Pixel Interactions in Texture Pyramids

This paper investigates how structures of pairwise pixel interactions are changing at subsequent levels of Gaussian or Laplacian pyramids representing spatially homogeneous image textures. Structural differences between the parent and child levels of the pyramid are analysed using the modelbased interaction maps (MBIM) describing relative interaction energies in a generic Gibbs random field mod...

Hopf bifurcation analysis of a diffusive predator-prey model with Monod-Haldane response

In this paper, we have studied the diffusive predator-prey model with Monod-Haldane functional response. The stability of the positive equilibrium and the existence of Hopf bifurcation are investigated by analyzing the distribution of eigenvalues without diffusion. We also study the spatially homogeneous and non-homogeneous periodic solutions through all parameters of the system which are spati...

Accuracy of the Regularised Dynamic Programming Stereo

Binocular stereo is an ill-posed problem that has to be regularised with respect to partial occlusions and homogeneous textures for obtaining a unique solution. We analyse typical errors of the dynamic programming stereo based on a probabilistic regularisation of partial occlusions. Experiments show that the reconstruction is accurate until occlusions do not prevail over the binocularly visible...
