Realistic Cosmetic Plastic Surgery Simulation Based on the Golden Ratio

Facial cosmetology is usually operated by surgeons on the basis of clinical experiences and is full of risks because of the lack of objective criteria and auxiliary tools. The available plastic simulation systems are not easy to manipulate. This paper presents a realistic cosmetic plastic surgery simulation framework guided automatically by golden ratio data, which is suitable for personalized realistic facial models from 3D laser scan. A golden ratio facial mask is made based on the ideal golden ratio facial mask data, with reference to the facial ratio of goodlooking groups of eastern people. The plastic design for the region of interest will be driven automatically by Laplacian coordinates deformation, based on the matched characteristic points and lines of the golden ratio facial mask to set the boundary conditions. The evaluation from clinical surgeons shows that the new plastic simulation system is practical and will be widely used in clinical operations.
