Structure-Coherent Deep Feature Learning for Robust Face Alignment

Area of Science:

• Computer Vision
• Machine Learning
• Artificial Intelligence

Background:

• Existing face alignment methods often neglect crucial facial structure cues.
• Robustness to occlusions and large poses remains a significant challenge in face alignment.

Purpose of the Study:

• To propose a structure-coherent deep feature learning method for enhanced face alignment.
• To improve the robustness of face alignment detectors against challenging conditions.

Main Methods:

• Utilized a landmark-graph relational network to model relationships between facial landmarks.
• Implemented dynamic neighborhood adaptation to mitigate noise from occluded landmarks.
• Introduced a relative location loss to enforce structural regularization.

Main Results:

• Demonstrated superior performance on WFLW, COFW, and 300W benchmarks.
• Achieved significant robustness in challenging scenarios, leading to low failure rates on COFW and WFLW.
• The method is compatible with existing convolutional backbones.

Conclusions:

• Explicitly modeling facial landmark structure significantly enhances face alignment performance.
• The proposed method offers a robust solution for face alignment, particularly in difficult real-world conditions.
• The approach provides a valuable contribution to the field of computer vision and facial analysis.
