Beltrami Denoising Algorithm for Ink-Jet Printing Material Image
Image denoising for ink-jet printing material is an active research field in ink-jet printing material processing aiming at the removal of noise. In this paper, we present a novel denoising algorithm within the framework of Beltrami manifold and shape prior technology. Beltrami manifold is applied to enhance image features while preserving natural fine structures. The shape prior term for the deformable framework through a non-linear energy term is designed to attract a shape towards the Beltrami manifold at given directions. The visual and quantitative evaluation of experimental results has demonstrated the efficiency of the proposed algorithm for removing noise.
