In this paper, we propose and develop a novel hue-preserving color image
restoration model. In the proposed model, saturation-value total variation is used as
the regularization term. In order to reduce hue loss during regularization, the huepreserving technique is incorporated into the proposed energy functional. We then
rewrite the proposed model equivalently into a three-block separable convex version
and apply an alternating direction method of multipliers based algorithm to solve the
proposed equivalent model numerically. We also give the convergence analysis of the
proposed algorithm. Numerical examples are presented to demonstrate that the performance of the proposed restoration model is better than that of other testing methods
in terms of visual quality and some criteria such as peak signal-to-noise ratio, structure
similarity, and spatial-CIELAB color error.
