本文介紹一全自動電腦視覺技術，可進行變臉、醫學美容整形、變老變年輕、換膚、變換眉型、下巴、髮際線修改後、最佳化人臉比例等預測模型結果。應用上除了醫美應用，也普遍應用於娛樂電影替身效果。而近年來全球盛行的美妝與保養風潮、美容、整形等等領域，皆可運用人臉特徵註冊和變形達到更精準地分析、預測和模擬效果。本文技術包含人臉影像特徵擷取模型、全自動影像註冊和仿射變形、無縫融合等技術，深入介紹醫學美容整形模擬影像技術的應用和其發展性。

This paper presents a fully automatic computer vision system for producing simulated/prediction outcomes after facial plastic surgery. The system is able to simulate the outcomes of aging, becoming younger, skin replacement, surgery of eye browses, eyes, noses, mouths, chin, cheek and hairlines. Apart from simulation for facial plastic surgery, the technique is also popularly applied to fi lming and gaming industries such as avatars. The technology introduced in this paper includes automatic facial landmark detection models, image registration, image transformation and fusion techniques. We further introduce the applications of the simulation technology of facial plastic surgery and potentials of the technology.
