anyone with sense of sketching knows that face golden pentagonal area, which formed by the eyebrow arch to the cheekbones to the nasal bones, and the upper jaw bone, does not move. no matter how exaggerated expressions can be, no matter what changes in fat or thin the faces appear, no matter captured at what angle, this pentagonal area is remained relatively fixed geometric relationship. based on these unchanging factors, we invented the bone point pentagonal face recognition algorithm gface, using deep learning methods. this algorithm is not interfered by skin color and ethnicity, and can well avoid expression changes, beard camouflage, angle deviation, and hairline changes , glasses decoration, mouth occlusion and other environmental factors.
