ABSTRACT
  • Using a novel characterization of texture, we
    propose an image decomposition technique that can
    effectively decomposes an image into its cartoon
    and texture components.
  • The characterization rests on our observation
    that the texture component enjoys a blockwise
    low-rank nature with possible overlap and shear,
    because texture, in general, is globally
    dissimilar but locally well patterned.
  • More specifically, one can observe that any local
    block of the texture component consists of only a
    few individual patterns.
  • Based on this premise, we first introduce a new
    convex prior, named the block nuclear norm (BNN),
    leading to a suitable characterization of the
    texture component.
  • We then formulate a cartoon-texture decomposition
    model as a convex optimization problem, where the
    simultaneous estimation of the cartoon and
    texture components from a given image or degraded
    observation is executed by minimizing the total
    variation and BNN.

ABSTRACT
  • In addition, patterns of texture extending in
    different directions are extracted separately,
    which is a special feature of the proposed model
    and of benefit to texture analysis and other
    applications.
  • Furthermore, the model can handle various types
    of degradation occurring in image processing,
    including blur missing pixels with several types
    of noise.
  • By rewriting the problem via variable splitting,
    the so-called alternating direction method of
    multipliers becomes applicable, resulting in an
    efficient algorithmic solution to the problem.
  • Numerical examples illustrate that the proposed
    model is very selective to patterns of texture,
    which makes it produce better results than
    state-of-the-art decomposition models.

EXISTING METHODS
  • (isotropic) Total Variation
  • G-norm
  • Numerical implementations and applications

PROPOSED METHOD
  • A cartoon-texture decomposition model with a
    novel texture prior named the Block Nuclear Norm
    (BNN).
  • Using BNN, our model interprets the texture
    compo- nent as the combination of blockwise
    low-rank matrices with possible overlap and
    shear, which leads to a suitable char-
    acterization of globally dissimilar but locally
    well-patterned nature of texture.
  • The convex optimization problem associated with
    the proposed model is efficiently solved by ADMM.
