A multiscale representation-based denoising method for spherical data contaminated with Poisson noise, the multiscale variance stabilizing transform on the sphere (MS-VSTS), has been recently proposed. This paper first extends this MS-VSTS to spherical 2D-1D, where the two first dimensions are longitude and latitude, and the third dimension is a meaningful physical index such as energy or time. Then we introduce a novel multichannel deconvolution built upon the 2D-1D MS-VSTS, which allows to…

It is shown how these transforms can be used in denoising and especially in a Combined Filtering Method, which uses both the wavelet and the curvelet transforms, thus benefiting from the advantages of both transforms.
