A novel Shape Constrained Feature-based Active Contour model for lips/mouth segmentation in the wild
作者：
Highlights：
• Propose a novel joint formulation of contour and shape for lips segmentation.
• Robustly segment lips under challenging environment and complex background.
• The energy functional is composed of 5 terms based on the Chan-Vese functional.
• The shape space is defined by a 2D.
• Experiments are conducted from the MBGC, VidTIMIT, JAFFE, and LFW databases.
