NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: pyramidal Lucas–Kanade method
Context triple: [Kanade–Lucas–Tomasi feature tracker, relatedTo, pyramidal Lucas–Kanade method]
  • A. Lucas–Kanade optical flow algorithm chosen
    The Lucas–Kanade optical flow algorithm is a widely used computer vision method for estimating the motion of features between consecutive images by assuming locally constant motion and solving a least-squares problem.
  • B. Horn–Schunck optical flow method
    The Horn–Schunck optical flow method is a classic global variational approach in computer vision that estimates dense motion fields between image frames by enforcing both brightness constancy and smoothness constraints.
  • C. Kanade–Lucas–Tomasi feature tracker
    The Kanade–Lucas–Tomasi feature tracker is a widely used computer vision algorithm for robustly tracking distinctive image features across video frames, building on the Lucas–Kanade optical flow method with Tomasi’s feature selection criteria.
  • D. Shi–Tomasi corner detector
    The Shi–Tomasi corner detector is a computer vision algorithm that identifies good feature points (corners) in images for robust tracking and recognition tasks.
  • E. Harris corner detector
    The Harris corner detector is a foundational computer vision algorithm used to identify interest points or corners in images for tasks like tracking, matching, and 3D reconstruction.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.

Provenance (3 batches)

The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
