Definition

Signature sample synthesis is the generation of synthetic signature from a user’s signature samples. It is a special case of handwriting sample synthesis which generates novel handwriting in a particular person’s handwriting style. A handwriting or signature synthesis system has two basic modules: the modeling module and the synthesis module. In the modeling module, the system collects handwriting/signature samples of a specific writer (online or off-line) and identifies and stores the basic characteristics of samples (e.g., shape and spatial layout). In the synthesis module, synthetic glyphs are generated from the stored templates, and they may be further aligned and connected to form synthetic handwriting data.
