Previous work … WebIn this paper, we study low-rank matrix recovery problem from linear measurements perturbed by ℓ 1 -bounded noise and sparse noise that can arbitrarily change an adversarially chosen ω-fraction of the measurement vector. For Gaussian measurements with nearly optimal number of measurements, we show that the nuclear-norm …

Web3.2. Incomplete low-rank matrix construction. In each matrix Qi, some pixels are unreliable since it may be damaged by impulsive noise, corrupted by Gaussian noise with large amplitude or from mismatched patches. Here, we set the values of these unreliable pixels to zeros, and discuss the restoration of low-rank matrix based on pixels with high
