A superresolution method is presented with a conjugate-gradient procedure under a nonnegativity constraint. The method is based on the property of a nonnegative object that its band-limited spectrum is the autoconvolution of a spectrum with a half-band limit, and the method is capable of doubling the band limit of an image. Computer simulations are conducted to investigate the performance of the present method.
