    A Fast TVL1-L2 Minimization Algorithm for Signal Reconstruction from Partial Fourier Data 

    Yang, Junfeng; Zhang, Yin; Yin, Wotao (2008-10)
    Recent compressive sensing results show that it is possible to accurately reconstruct certain compressible signals from relatively few linear measurements via solving nonsmooth convex optimization problems. In this paper, ...

    A Fast Algorithm for Edge-Preserving Variational Multichannel Image Restoration 

    Yang, Junfeng; Yin, Wotao; Zhang, Yin; Wang, Yilun (2008-07)
    We generalize the alternating minimization algorithm recently proposed in [32] to effciently solve a general, edge-preserving, variational model for recovering multichannel images degraded by within- and cross-channel ...

    A Curvilinear Search Method for p-Harmonic Flows on Spheres 

    Goldfarb, Donald; Wen, Zaiwen; Yin, Wotao (2008-01)
    The problem of finding p-harmonic flows arises in a wide range of applications including micromagnetics, liquid crystal theory, directional diffusion, and chromaticity denoising. In this paper, we propose an innovative ...

    Iterative Reweighted Algorithms for Compressive Sensing 

    Chartrand, Rick; Yin, Wotao (2008-01)
    The theory of compressive sensing has shown that sparse signals can be reconstructed exactly from many fewer measurements than traditionally believed necessary. In [1], it was shown empirically that using lp minimization ...
