2D facial landmark model design by combining key points and inserted points
作者：
Highlights：
• An optimized landmark model (LM) for face representation is developed.
• The landmarks are divided into key points and inserted points.
• Key points include anatomical and mathematical landmarks.
• Inserted points help describe contours and are optimized by iterative search.
• The LM shows superiority in delicate and efficient face shape representation.
