Saliency-guided Luminance Enhancement for 3D Shape Depiction
We present a novel saliency-guided shading scheme for 3D shape depiction incorporating the mesh saliency into luminance enhancement in this paper.Using a distanced-based mesh saliency computation,we propose a new perceptualsaliency measure which can depict surface salient regions.Due to the visual salient regions,we emphasize the details and the overall shape of models by locally enhancing the highfrequency of vertex luminance.The enhanced strength is not controlled by user whereas it is determined by the surface shapes.Experimental results demonstrate that our method displays satisfying results obtained with Phong shading,Gooch shading and cartoon shading.Compared to previous techniques,our approach can effectively improve shape depiction without impairing the desired appearance.
