Abstract:
This paper proposes a stable Super Resolution(SR) reconstruction algorithm to image analysis for enhancing the quality of images. It proposes Lorenztain-based Maximum A Probability(MAP) algorithm by modeling the edge image, which is iterated by the Lorentzwidth parameter adaptively to modify the reconstruction. Experimental results demonstrate validity and superiority of the algorithm, which can get ideal and stable reconstructions when applying to image forensics practices.
