Vertical drift-correction algorithms (scanpath_studio/alignment.py)

  The ten vertical drift-correction / line-assignment algorithms (attach, chain,
  cluster, compare, merge, regress, segment, split, stretch, warp) are a native
  port — adapted and modified — of the reference implementations accompanying:

    Carr, J. W., Pescuma, V. N., Furlan, M., Ktori, M., & Crepaldi, D. (2021).
    Algorithms for the automated correction of vertical drift in eye-tracking
    data. Behavior Research Methods, 54, 287-310.

Bundled demo corpus (scanpath_studio/sample_data/)

  The demo tables and stimulus images are a small subset of OneStop Eye
  Movements (3 participants x 2 articles), with the corpus's own linguistic
  annotations:
