In this paper, we present a modified projected Landweber super-resolution algorithm for resolution enhancement of passive millimeter wave images. In this algorithm, we implement the Landweber iterations as the main image restoration scheme, and a projection-based adjustment for enforcing constraints after each Landweber iteration is completed to complete spectral extrapolation, lastly we implement...
Passive millimeter wave (PMMW) images have inherently the problem of poor resolution due to limited aperture dimension. Thus efficient post-processing is necessary to achieve resolution improvement. In this paper we present a wavelet-based algorithm for resolution enhancement of passive millimeter wave images. In the algorithm, we implement the wavelet-based Landweber iterations as the main image...
