We present a novel multi-view denoising algorithm. Our
algorithm takes noisy images taken from different viewpoints
as input and groups similar patches in the input images using
depth estimation. We model intensity-dependent noise in lowlight
conditions and use the principal component analysis and
tensor analysis to remove such noise. The dimensionalities for
both PCA and tensor analysis are automatically computed in
a way that is adaptive to the complexity of image structures in
the patches. Our method is based on a probabilistic formulation
that marginalizes depth maps as hidden variables and
therefore does not require perfect depth estimation. We validate
our algorithm on both synthetic and real images with
different content. Our algorithm compares favorably against
several state-of-the-art denoising algorithms.
