Erratum to “Luminance Learning for Remotely Sensed Image Enhancement Guided by Weighted Least Squares”

In the above article
[1]
, the model in
(1)
should be revised as
\begin{equation*}\min _{\mathcal{I}^{\mathcal{B}}}\left\{\left(\mathcal{I}-\mathcal{I}^{\mathcal{B}}\right)^{2}+\lambda\left(a_{x}(\mathcal{I})\left(\frac{\partial \mathcal{I}^{\mathcal{B}}}{\partial x}\right)^{2}+a_{y}(\mathcal{I})\left(\frac{\partial \mathcal{I}^{\mathcal{B}}}{\partial y}\right)^{2}\right)\right\} \end{equation*}
to be minimized for
${\mathcal {I}}^{\mathcal {B}}$
.
