Abstract
Editing a photo-realistic gradient mesh is a tough
task. Even only editing the colors of an existing gradient
mesh can be exhaustive and time-consuming. To facilitate
user-friendly color editing, we develop an example-based color
transfer method for gradient meshes, which borrows the color
characteristics of an example image to a gradient mesh. We
start by exploiting the constraints of the gradient mesh, and
accordingly propose a linear-operator-based color transfer
framework. Our framework operates only on colors and color
gradients of the mesh points and preserves the topological
structure of the gradient mesh. Bearing the framework in
mind, we build our approach on PCA-based color transfer.
After relieving the color range problem, we incorporate a
fusion-based optimization scheme to improve color similarity
between the reference image and the recolored gradient mesh.
Finally, a multi-swatch transfer scheme is provided to enable
more user control. Our approach is simple, effective, and
much faster than color transferring the rastered gradient
mesh directly. The experimental results also show that our
method can generate pleasing recolored gradient meshes.
