Estimating the pen trajectories of multi-path static scripts using hidden Markov models
Emli-Mari Nel, Johan A. du Preez, B. M. Herbst · 2005
Static handwritten scripts are available only as images on documents and by definition do not contain dynamic information. This study is about extracting dynamic information from a static handwritten script, specifically the sequence of pen positions that created the script. We assume that a dynamic representative of the static image is available (a different version typically obtained during an earlier registration process). A hidden Markov model (HMM) of the static image is compared with the dynamic representative to extract the dynamic information from the static image.
