Video Texture Synthesis using Fractal Processes

摘要

In this paper we propose a new approach for the synthesis of natural video textures. After generalizing the bidimensional extended self-similar (ESS) model to the three dimensional (3D) case we want to generate samples of 3D-ESS fields on a discrete grid. The video texture is modeled according to the 3D-ESS model. The autocorrelation functions (ACFs) of the increments of the original video texture, at different spatial and temporal scales, are estimated according to the 3D-ESS model. A synthetic 3D-ESS field, whose increments have t he same ACFs of the corresponding ones of the given prototype, is generated using the incremental Fourier synthesis algorithm.
