Overview of TOHG

Text-to-Online Handwriting Generation (TOHG) refers to the task of synthesizing realistic pen trajectories $(G_i)$ conditioned on textual content $(T)$ and style reference $(S_i)$.

DiffInk vs. Character–Layout Decoupled Approaches

(a) A two-stage pipeline combining handwritten font generation with layout post-processing; (b) DiffInk (Ours), which takes text and a style reference to directly output complete text lines. Unlike the two-stage pipeline, DiffInk generates more natural character connections rather than mechanically stitching bounding boxes.
