US Patent 9224248 Method of virtual makeup achieved by facial tracking

Method of applying virtual makeup and producing makeover effects to 3D face model driven by facial tracking in real-time includes the steps: capturing static or live facial images of a user; performing facial tracking of facial image, and obtaining tracking points on captured facial image; and producing makeover effects according to tracking points in real time. Virtual makeup can be applied using virtual makeup input tool such as a user's finger sliding over touch panel screen, mouse cursor or an object passing through makeup-allowed area. Makeup-allowed area for producing makeover effects is defined by extracting feature points from facial tracking points and dividing makeup-allowed area into segments and layers; and defining and storing parameters of makeup-allowed area. Virtual visual effects including color series, alpha blending, and/or superposition are capable of being applied. Makeover effect takes into account of lighting condition, facial posture rotation, face size scaling, and face translation, respectively.
