Why handwriting segmentation can be misleading?

This paper presents a handwriting generation model based on a kinematic theory of rapid human movements. Handwriting is described as the vectorial sum of formal strokes. These strokes are characterized by a velocity profile that can be described by a delta-lognormal equation. The segmentation algorithm that results from this model allows a comparison of this formal approach with some operational and simpler segmentation methods, in the context of the unicity of the allograph representation.
