The injection scheme provides an efficient way for CS- and MRA-based pansharpening approaches. Within this paradigm, the estimation of gains is one keys to outcomes, which has attracted much attention in community. Most existing models are derived from regression methodology. Hence, reference indispensable estimation. However, unavailable practice, therefore, usually performed at a degraded scale. This article devoted without reference. A hybrid-scale (HS) estimation, involves both...
