The vector decomposition problem (VDP) has been proposed as a computational problem on which to base the security of public key cryptosystems. ...
We give a generalisation and simplification of the results of Yoshida on the VDP. ...
Acknowledgements We thank Iwan Duursma, Seung-Kook Park, Maura Paterson and a number of anonymous referees for helpful comments on a much earlier draft of the paper. ...

we proposed a nonlocal-approximate sparsity regularizer in analysis domains by minimizing the sum of the 2 l norms of those vectors with the same nonzero pattern like signal vectors. ...
In this paper, based on a simple observation that the non-zero entries of the sparsity vector in various image analysis domains should be also approximate when the relevant signal values are proximate, ...
The authors would like to thank three anonymous reviewers for their valuable comments and constructive suggestions. ...

A celebrated result indicates that if a synthesis frame is chosen for reconstruction, then its canonical dual frame is the analysis frame that performs decomposition, yielding coefficients that minimizes ...
However, we present some conditions on a dual frame so that the minimizer of the l1-norm can be derived from the coefficients of the dual frame. ...
The composition of the reconstruction operation after the decomposition operation must be an identity operation. ...
