Human Orientation Estimation Under Partial Observation
2024 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)Reliable Human Orientation Estimation (HOE) from a monocular image is critical for autonomous agents to understand human intention. Significant progress has been made in HOE under full observation. However, the existing methods easily make a wrong prediction under partial observation and give it an unexpectedly high confidence.

Improved Anisotropic Gaussian Filters
Image Analysis and StereologyElongated anisotropic Gaussian filters are used for the orientation estimation of fibers. In cases where computed tomography images are noisy, roughly resolved, and of low contrast, they are the method of choice even if being efficient only in virtual ...
