Segmenting Dynamic Textures with Ising Descriptors, ARX Models and Level Sets

  title={Segmenting Dynamic Textures with Ising Descriptors, ARX Models and Level Sets},
  author={Atiyeh Ghoreyshi and Ren{\'e} Vidal},
We present a new algorithm for segmenting a scene consisting of multiple moving dynamic textures. We model the spatial statistics of a dynamic texture with a set of second order Ising descriptors whose temporal evolution of is governed by an AutoRegressive eXogenous (ARX) model. Given this model, we cast the dynamic texture segmentation problem in a variational framework in which we minimize the spatial-temporal variance of the stochastic part of the model. This energy functional is shown to… CONTINUE READING
