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

In the above article [1] , model in ref-type="disp-formula" rid="deqn1" xmlns:xlink="http://www.w3.org/1999/xlink">(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 y}\right)^{2}\right)\right\} \end{equation*} to minimized for ${\mathcal {I}}^{\mathcal {B}}$ .
