Decomposition of Dynamic Textures Using Morphological Component Analysis: A New Adaptative Strategy

The research context of this work is dynamic texture analysis and characterization. Many dynamic textures can be modeled as a large scale propagating wave and local oscillating phenomena. The Morphological Component Analysis algorithm is used to retrieve these components using a well chosen dictionary. We define a new strategy for adaptive thresholding in the Morphological Component Analysis framework, which greatly reduces the computation time when applied on videos. Tests on synthetic and real image sequences illustrate the efficiency of the proposed method and future prospects are finally exposed.
