Artistic relighting of paintings and drawings
2015
The Visual Computer
We present a practical solution to the problem of subject relighting in paintings and drawings. Our interactive technique uses 3-D shading proxies and can be applied to objects with arbitrary geometries. Given a user-provided guess for the shading of an object in a painting/drawing and its corresponding target shading, we refine them using shading-color correlation and a multi-scale scheme. These refined shadings are then used to create a multi-channel shading-ratio image to perform relighting,
