New framework detects geometric biases in 3D face reconstruction

Researchers have developed a new framework to identify and quantify geometric biases in 3D face reconstruction models. By analyzing surface curvature using the Laplace-Beltrami Operator, the framework generates detailed error maps that better correlate with human perception than traditional methods. Experiments revealed systematic age-related biases, with preliminary evidence of gender and ethnic biases, highlighting the need for curvature-aware evaluation to ensure fairness and precision in 3D face reconstruction.
