For　the　purpose　of　the　implementation　and　the　improvement　for　POCS　super-resolution　reconstruction,　we　design　a　simulation-correction　iteration　method　to　reconstruct　high-resolution　images　according　to　the　theory　of　POCS,　and　also　propose　an　improvement　to　reduce　the　amount　of　Gibbs　artifacts　present　on　the　edges　of　the　high-resolution　reconstructed　image,　which　weights　the　blur　PSF　centered　at　an　edge　pixel　with　an　exponential　function,　and　consequently　decreases　the　coefficients　of　the　modified　PSF　in　the　direction　orthogonal　to　the　edge.　The　proposed　algorithm　is　validated　using　both　simulated　and　real　sequences.　Experimental　results　show　that　the　proposed　algorithm　is　simple　and　available,　and　furthermore　reduces　effectively　the　visibility　of　edge　artifacts　and　produces　high-resolution　images　of　good　quality.
