Abstract
The multi-frame SRR (Super Resolution
Reconstruction) algorithm has become the significant theme in
digital image research society in the last ten years because of its
performance and its cost effectiveness hence many robust norm
functions (both redescending and non-redescending influence
functions) have been usually incorporated in the multi-frame
SRR framework, which is combined a stochastic Bayesian
approach and a regularization technique into the unify SRR
framework. Consequently, this paper thoroughly presents
experimental exploration of an iterative SRR algorithm based on
several robust norm functions such as zero-redescending
influence functions (Tukey’s Biweight, Andrew’s Sine and
Hampel), nonzero-redescending influence functions (Lorentzian,
Leclerc, Geman&McClure, Myriad and Meridian) and nonredescending
influence functions (Huber). This paper utilizes
two standard images of Lena and Susie (40th) for pilot studies
and fraudulent noise patterns of AWGN, Poisson, Salt&Pepper,
and Speckle of several magnitudes are used to contaminate these
two standard images. The comparative experiment has been
done by thoroughly changing all parameters such as step-size,
regularization parameter, norm constant parameter in order to
obtain the maximum PSNR (peak-signal-to-noise ratio).
