abstract = {<p style="text-align: justify;">This paper aims to present a decolorization strategy based on perceptual consistency
and dark channel prior. The proposed model consists of effective fidelity terms and a prior term.
We use the $\mathcal{l}$<sub>0</sub>-norm to control the sparsity of the dark channel prior. To solve the non-convex
minimization problem, we employ the split and penalty technique to simplify the minimization
problem and then solve it by the carefully designed iteration scheme. Besides, we show the
convergence of the algorithm using Kurdyka-Lojasiewicz property. The numerical evaluation in
comparison with other state-of-the-art methods demonstrates the effectiveness of the proposed
method.</p>},
