Impulsive Noise Robust Sparse Recovery via Continuous Mixed Norm
Amirhossein Javaheri, Hadi Zayyani, Mario A. T. Figueiredo +1
This paper investigates the problem of sparse signal recovery in the presence of additive impulsive noise. The heavytailed impulsive noise is well modelled with stable distribution…
Recovery of Missing Samples Using Sparse Approximation via a Convex Similarity Measure
Amirhossein Javaheri, Hadi Zayyani, Farokh Marvasti
In this paper, we study the missing sample recovery problem using methods based on sparse approximation. In this regard, we investigate the algorithms used for solving the inverse…
On Higher Order Positive Differential Energy Operator
Amirhossein Javaheri, Mohammad Bagher Shamsollahi
The higher order differential energy operator (DEO), denoted via , is an extension to the second order famous Teager-Kaiser operator. The DEO helps measuring the higher ord…
A Convex Similarity Index for Sparse Recovery of Missing Image Samples
Amirhossein Javaheri, Hadi Zayyani, Farokh Marvasti
This paper investigates the problem of recovering missing samples using methods based on sparse representation adapted especially for image signals. Instead of -norm or Mean S…
