We observe that given a set of good similar patches, their distribution is not necessarily centered at the noisy reference patch and can be approximated by a Gaussian component.

Using these three frames, we render a new frame with the same time stamp as the non-reference frame but from the viewpoint of the reference sensor.

In this paper, we present a no-reference image denoising quality assessment method that can be used to select for an input noisy image the right denoising algorithm with the optimal parameter setting.

Based on this subspace constraint, our method formulates depth map enhancement as a low-rank matrix completion problem.
