Description: Dynamic textured sequences are scenes with complex motion patterns due to the interactions between the multiple moving components. Examples of dynamic textures include blowing leaves, flickering flames and water splashing in a fountain. In our approach, the images of the sequence are interpreted as the output of a linear autoregressive process driven by white Gaussian noise. We extend earlier work by increasing the amount temporal information included when learning the motion in the scene allowing the models to capture motion patterns which extend over multiple frames, thereby, increasing the perceptual accuracy of the synthesized results. To overcome problems of dynamic model stability, we apply the Maximum Entropy Method (Burg, 1975) for parameter estimation, which is reliably stable on smaller samples of training data, even with higher-order dynamics.
