METHOD FOR ERROR RECOVERY FOR RECOGNISING A USER PRESENTATION THROUGH ASSESSING THE RELIABILITY OF A LIMITED SET OF HYPOTHESES

摘要

For recognizing a user presentation that is represented as a plurality of physical components through assessing a feasibility of a provisional recognition, various presentation components thereof are recognized in successive steps. In particular, along with the successive steps of the recognizing, a limited set of hypotheses is built for the presentation. At predetermined instants along the steps, these hypotheses are matched with an associated reliability level. Upon non-meeting of the reliability level with respect to one or more components as signalling an impending dead-end situation, the feasibility is improved by for the latter such component driving the method to an error recovery procedure to improve the reliability of one or more elements of the limited set.
