A New Trend in Optimization on Multi Overcomplete Dictionary toward Inpainting
SeyyedMajid Valiollahzadeh, Mohammad Nazari, Massoud Babaie-Zadeh +1
Recently, great attention was intended toward overcomplete dictionaries and the sparse representations they can provide. In a wide variety of signal processing problems, sparsity s…
Approximate Sparse Decomposition Based on Smoothed L0-Norm
Hamed Firouzi, Masoud Farivar, Massoud Babaie-Zadeh +1
In this paper, we propose a method to address the problem of source estimation for Sparse Component Analysis (SCA) in the presence of additive noise. Our method is a generalization…
A First Step to Convolutive Sparse Representation
Hamed Firouzi, Massoud Babaie-Zadeh, Aria Ghasemian +1
In this paper an extension of the sparse decomposition problem is considered and an algorithm for solving it is presented. In this extension, it is known that one of the shifted ve…
