Pan-sharpening with Structural Consistency and L1/2 Gradient Prior

Most methods focus on spatial intensity preservation while the proposed method tends to preserve the consistency of the spatial structure information. In addition, an L 1 -aL 2 metric is used to estimate L 1/2 gradient prior.

The alternating direction method of multipliers (ADMM) and the difference of convex algorithm (DCA) are used to guarantee the convergence of the algorithm. A large number of experiments show that the proposed method has obvious advantages compared with other advanced methods both subjectively and objectively.
