We propose a fast algorithm solving the inverse problem of resolution enhancement (superresolution) with edge-preserving regularization. An additive and multiplicative half-quadratic linearization scheme are compared and we show that the additive form is superior as all operations can be implemented in the frequency domain using the FFT.
