Abstract
A process and system for modeling, learning and synthesizing cursive handwriting in a user's personal handwriting style. The handwriting synthesis system and process described herein addresses the problem of learning the personal handwriting style of a user based on limited handwriting samples and producing novel scripts of the same style. The handwriting synthesis process includes segmenting handwriting samples into individual characters using a two-level writer-independent segmentation process, aligning samples of the same character into a common coordinate frame, and learning and modeling the individual character. Synthesis of handwriting is performed by generating individual letters from the models and concatenating the letters using a conditional sampling algorithm. The result is a smooth and fluid connection between letters that successfully mimics the personal handwriting style of a user.
