Pansharpening / Linear Regression
‹ Brovey Example | ● | ColorMatching ›
Pansharpening a la Linear Regression:
$Pan = \alpha R + \beta G + \gamma B + \theta NIR + c$
- Determine $\alpha, \beta, \gamma, \theta$ und $c$ by multiple linear regression
- Then $V' = Pan \cdot \frac{V}{\alpha R + \beta G + \gamma B + \theta NIR + c}$
- Brovey is special case for $\alpha=\beta=\gamma=\frac13$, $\theta=c=0$.
