In this paper we are interested in discuss the symmetry property and construction of an m-band compactly supported orthonormal multiwavelets related to the filters with different symmetric centers. With the development of the several equivalent conditions on this type of symmetry in terms of...

This paper proposes a novel strategy for depth video denoising in RGBD camera systems. Depth map sequences obtained by …. The authors approached this limitation by decoupling depth map upscaling from the temporal denoising step. Thereby …, denoising is processed on raw pixels including uncorrelated pixel-wise noise distributions. The authors' denoising methodology …

To estimate a possibly multivariate regression function g under the general regression setup, y=g+ϵ, one can use wavelet thresholding as an alternative to conventional nonparametric regression methods. Wavelet thresholding is a simple operation in the wavelet domain that selects a subset of...
