Stability and stationarity of cursive handwriting

摘要

Handwriting is considered as the output of a space variant imaging system equivalent to the writer. This system is described by the parameters of the synthesis of letters from a given model. A statistical analysis of the variations of this system on a set of successive pages leads to the extraction of writer features as well as the segmentation of the text into short-time stationarity domains to be related to “rhythms of writing”.
