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

Read the original on arXiv Computer Vision →

The paper introduces a geometry‑driven shadow harmonisation pipeline for composited faces that preserves albedo by applying a per‑pixel gain field derived from a rasterised 3D face proxy. The method estimates key‑light direction from host cues, computes surface normals and cast shadows, and applies a controlled, monotonic darkening operation that never alters chromaticity or identity. Experiments on analytic face heightfields show that the default parameters modify over half the face pixels while maintaining hue invariance and avoiding repainting the donor face.

Fidelity Preference, Not Demographic Preference: A Pixel-Level Attribute-Sensitivity Audit of Image Aesthetic/Preference Scorers

The study audits four image aesthetic scorers—LAION-Aesthetics, PickScore, ImageReward, and HPSv2—using pixel‑level interventions on skin tone and body type in both synthetic and real images. It finds that most scorers exhibit a fidelity preference: unaltered images receive the highest scores, while perturbations in either direction are penalized in an inverted‑U pattern, and this effect is largely independent of the skin operator. Synthetic‑only audits are misleading, as the apparent preference for darker skin in synthetic faces reverses or weakens when evaluated on real faces, and cross‑scorer results vary widely, underscoring the need for real‑data, within‑image causal isolation to accurately assess demographic bias.
