This study presents a comprehensive digital image processing analysis of the granite wall surfaces in the King's Chamber of the Great Pyramid of Khufu (Great Pyramid of Giza). Using seven distinct image processing techniques — CLAHE, False Color Heatmap, Negative Imaging, Multi-Angle Relief Mapping, Threshold Analysis, Emboss Filtering, and Solarize/Gamma Correction — applied systematically to six independent source photographs obtained from different cameras, angles, lighting conditions, and time periods, the study identifies consistent surface anomalies on the western wall (behind the sarcophagus). Key findings include: (1) an anthropomorphic facial form with symmetrical eye-position dark areas and a continuous nasal line spanning at least four granite blocks; (2) a Uraeus (sacred cobra) form directly above the face, consistent with classical Egyptian royal iconography; (3) anatomically proportional shoulder and torso structures below the face; (4) a guardian serpent figure on the adjacent wall; and (5) a statistically significant surface density anomaly on the western wall compared to other chamber walls, consistently observed across all six independent source images. While pareidolia remains a viable alternative explanation for individual elements, the convergence of five iconographically consistent elements in correct anatomical proportions, their cross-block continuity, and their reproducibility across multiple independent sources challenge a simple pareidolia interpretation. The study recommends in-situ investigation using LiDAR scanning, multispectral imaging, RTI (Reflectance Transformation Imaging), and petrographic analysis to achieve definitive conclusions. This preliminary study suggests that the established archaeological assumption that the King's Chamber walls are "completely smooth and undecorated" warrants re-examination using modern digital image processing technologies.
