Abstract

The paper presents a geometry-driven method for harmonizing shadows in face compositing without altering the identity or texture of the donor face.

Reality Card

Core Claim

The proposed method allows for shadow harmonization in face swapping while preserving the original face's color and texture, achieving a mean gain of 0.938 across modified pixels.

Method / Result

The default parameters modify 56.5% of face pixels with a mean gain of 0.938.

Limitations

The method may suffer from double-shadowing effects on non-flat donor faces, which could affect the visual quality.
