abstract = "Shading for cel animation based on images is a recent research
topic in computer-assisted animation. This paper proposes an
image-based shading pipeline to give a 3D appearance to a 2D
character by inspecting the hand-drawn image directly. The
proposed method estimates normal vectors on the character's
outline and interpolates them over the remaining image. The method
does not limit the animator's creative process and requires
minimal user intervention. The resulting shading pipeline can be
easily applied to photorealistic and non-photorealistic 2D cel
animation. In the proposed method, the animator can easily
simulate environment reflections on the surface of 2D reflecting
objects. As far as the authors are concerned, the proposed
technique is the only one in the literature that is genuinely an
image-based method for 2D animation.",
