• Existing methods struggle to isolate invariant style features (e.g., slant, stroke width, curvature) while ignoring irrelevant noise in one-shot handwriting generation.limitation 85%
  Evidencepartial

  Existing methods still struggle to generate visually appealing and realistic handwritten images and adapt to complex, unseen writer styles, struggling to isolate invariant style features (e.g., slant, stroke width, curvature) while ignoring irrelevant noise.

  Implicationpartial

  Directly stated as a problem with existing methods in the abstract, though it is a general characterization rather than a specific citation of prior work.
