  • Abstract
    We present a new procedure for reconstructing the wavelet transforms of the angular harmonics of an image from the wavelet transforms of the angular harmonics of its projections. The relation is a convolution over scale, rather than over translation, and preservation of compact support of the wavelet basis functions after a derivative-Hilbert transform is not required. It generalizes a recently proposed procedure using exponential radial sampling and decouples over angular harmonics.<>
