  • A Continuous Max-Flow Approach to Minimal Partitions with Label Cost Prior 

    Yuan, Jing; Bae, Egil; Boykov, Yuri; Tai, Xue-Cheng (The authors, 2011)
    This paper investigates a convex relaxation approach for minimum description length (MDL) based image partitioning or labeling, which proposes an energy functional regularized by the spatial smoothness prior joint with ...
  • Efficient Global Minimization for the Multiphase Chan-Vese Model of Image Segmentation 

    Bae, Egil; Tai, Xue-Cheng (Springer Verlag, 2009)
    The Mumford-Shah model is an important variational image segmentation model. A popular multiphase level set approach, the Chan-Vese model, was developed as a numerical realization by representing the phases by several ...
  • A Fast Continuous Max-Flow Approach to Non-Convex Multilabeling Problems 

    Bae, Egil; Yuan, Jing; Tai, Xue-Cheng; Boykov, Yuri (The authors, 2011)
    This work addresses a class of multilabeling problems over a spatially continuous image domain, where the data fidelity term can be any bounded function, not necessarily convex. Two total variation based regularization terms ...
  • Global Minimization for Continuous Multiphase Partitioning Problems Using a Dual Approach 

    Bae, Egil; Yuan, Jing; Tai, Xue-Cheng (Springer Verlag, 2010)
    This paper is devoted to the optimization problem of continuous multi-partitioning, or multi-labeling, which is based on a convex relaxation of the continuous Potts model. In contrast to previous efforts, which are ...
  • On Semi-implicit Splitting Schemes for the Beltrami Color Image Filtering 

    Rosman, Guy; Dascal, Lorina; Tai, Xue-Cheng; Kimmel, Ron (Springer, 2011)
    The Beltrami flow is an efficient nonlinear filter, that was shown to be effective for color image processing. The corresponding anisotropic diffusion operator strongly couples the spectral components. Usually, this flow ...

  • Reconstructing Open Surfaces via Graph-Cuts 

    Wan, Min; Wang, Yu; Bae, Egil; Tai, Xue-Cheng; Wang, Desheng (The authors, 2011)
    A novel graph-cuts-basedmethod is proposed for reconstructing open surfaces from unordered point sets. Through a boolean operation on the crust around the data set, the open surface problem is translated to a watertight ...
  • A Study on Continuous Max-Flow and Min-Cut Approaches 

    Yuan, Jing; Bae, Egil; Tai, Xue-Cheng (IEEE, 2010)
    We propose and investigate novel max-flow models in the spatially continuous setting, with or without supervised constraints, under a comparative study of graph based max-flow / min-cut. We show that the continuous max-flow ...
