Variational OSV Decomposition Model for Color Image with Nonlinear Diffusion Regularization
Guodong Wang · Journal of Information and Computational Science · 2014
Image decomposition attracted much attention in recent years. Inspired by the work of Meyer, numerical methods have been proposed to carry out the decomposition of gray scale images. In this paper, we present a new model for color image decomposition. We extend the OSV (Osher-Sole-Vese) model from gray image to color image. We also modify the model by using nonlinear difiusion regularization as smooth term. To enhance the e‐ciency and reduce the complexity for solving the energy equation, the Split Bregman method is introduced. We compared our proposed method with the color TV (Total Variation) model. Experiments show the proposed method is a valid method for color image decomposition.
