This study introduces a new framework to improve head pose estimation using single RGB images. The enhanced method achieves higher accuracy and robustness in estimating head orientation, outperforming previous models.

Area of Science:

  • Computer Vision
  • Facial Analysis
  • Machine Learning

Background:

  • Head pose estimation is crucial for facial analysis and behavior understanding.
  • Existing methods like 6DRepNet face limitations in single-RGB scenarios, especially with complex poses and spatial modeling.
  • There's a need for improved head pose estimation accuracy and robustness.

Purpose of the Study:

  • To propose a geometry-aware enhanced framework for head pose estimation.
  • To address limitations in spatial discriminative region modeling and large-pose sample optimization.
  • To improve upon the baseline 6DRepNet model for single-RGB head pose estimation.

Main Methods:

  • Introduced a Spatial Recalibration Module, a Residual Pose Mapping Head, and a Pose-Aware Weighted Geodesic Loss.
  • Trained and evaluated the model using datasets like 300W-LP, AFLW2000, and BIWI.

    • Main Results:

    • The proposed method consistently outperformed the baseline 6DRepNet on AFLW2000 and BIWI datasets.
    • Mean Absolute Error (MAE) was reduced from 3.97 to 3.72 on AFLW2000 and 3.54 to 3.26 on BIWI.
    • Ablation studies confirmed the effectiveness and complementarity of the new components.

    Conclusions:

    • The proposed framework significantly enhances the accuracy and robustness of single-RGB head pose estimation.
    • The method effectively addresses challenges in spatial modeling and large-pose optimization without requiring additional data modalities.
    • The geometry-aware approach provides a promising direction for future head pose estimation research.
