Variational Layered Dynamic Textures
A dynamic texture is a generative model for video that treats the video as a sample from spatio-temporal stochastic process. One problem associated with the dynamic texture is that it cannot model video where there are regions of motion with different dynamics, e.g. a scene with smoke and fire. In this work, we introduce the layered dynamic texture model, which addresses this problem by introducing a separate state process for each region of motion. We derive the EM algorithm for learning the parameters of the model, and demonstrate the efficacy of the proposed model for the tasks of segmentation and synthesis of video.
