Illumination Handling & Geometric Detail Preservation

A key advantage of the SGC method is its robust handling of illumination inconsistencies and superior preservation of geometric details.

Feature Proposed Method Traditional Methods
Illumination Inconsistency
  • Handles complex lighting and shadows via SH-based physical model, ensuring robust 3D modeling.
  • Often struggle with varying illumination, leading to distortions and inaccuracies.
Geometric Detail Preservation
  • Bilateral edge-aware constraint preserves sharp boundaries and finer structural details.
  • Prone to blurred contours and distorted structures due to standard smoothness terms.
