This system has been developed in the context of research on Smart Meeting Rooms. The GMMs in our system are trained using two sets of features extracted from a text line. The first feature set is similar to feature sets used in signature verification systems before. It consists of information gathered for each recorded point of the handwriting, while the second feature set contains features extracted from each stroke. While both feature sets perform very favorably, the stroke-based feature set outperforms the point-based feature set in our experiments. We achieve a writer identification rate of 100\\% for writer sets with up to 100 writers. Increasing the number of writers to 200, the identification rate decreases to 94.75\\%.}, pdf = {https://publications.idiap.ch/attachments/reports/2005/liwiki-idiap-rr-05-70.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2005/liwiki-idiap-rr-05-70.ps.gz}, ipdmembership={learning}, }
