New method injects realistic shadows into composited faces

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method for face compositing that addresses the common issue of inconsistent lighting between a composited face and its background. This new technique, termed geometry-driven form-shadow injection, focuses on darkening the face rather than re-synthesizing it, thereby preserving identity, skin tone, and texture. The pipeline estimates a per-pixel gain field from a 3D face proxy to darken the linear RGB values, ensuring that the chromaticity is not altered. It also incorporates scene cues to estimate key-light direction and uses a three-parameter transfer function to control shadow magnitude, offering a more photorealistic result without altering the original face's identity.

    Geometry-Driven Shadow Harmonisation for Composited Faces: A Multiplicative, Albedo-Preserving Relighting Pipeline

    arXiv:2609.17740v1 Announce Type: new Abstract: Face swapping and face compositing pipelines routinely produce a face that is geometrically well aligned but photometrically implausible: the donor face carries flat, near-frontal studio illumination while the host body and backgrou…
