// Luminance Vectors, Laplacian Edges & Noise Residuals
Visual forensics analyzes optical characteristics across a digital photograph without relying on compression history. Inspect surface lighting vectors to confirm all subjects share the same light source, detect cut-and-paste boundaries using 2D Laplacian kernels, and surface sensor noise pattern discrepancies.
