Impulsive Noise Robust Sparse Recovery via Continuous Mixed Norm

1 code implementation12 Apr 2018 Amirhossein Javaheri, Hadi Zayyani, Mario A. T. Figueiredo, Farrokh Marvasti

In this paper, we exploit a Continuous Mixed Norm (CMN) for robust sparse recovery instead of $\ell_p$-norm.

A Convex Similarity Index for Sparse Recovery of Missing Image Samples

no code implementations25 Jan 2017 Amirhossein Javaheri, Hadi Zayyani, Farokh Marvasti

The proposed criterion called Convex SIMilarity (CSIM) index is a modified version of the Structural SIMilarity (SSIM) index, which despite its predecessor, is convex and uni-modal.
