Vision Club of Finland awards Vuokko Vuori
with Vision Prize 98
VCF has annually awarded the
best thesis in the area of MV technology research and application. The
received applications were concrete and practical and included industrial
potential. This year the winner is Vuokko Vuori, who made meritorious research
in adaptive real-time recognition of handwriting and published the results
in her Master of Science thesis. Congratulations to the winner of 3000
FIM award and many thanks to all of them, who applied to the competition.
Adaptation in on-line recognition of handwriting
Due to the increasing popularity
of hand-held computers, digital notebooks, and advanced cellular phones, automatic on-line
recognition of hand-written text has been gaining more interest lately.
The traditional methods of man-machine
communication, a keyboard and pointing devises, are very inconvenient to
use and expensive to implement when the size of the machine is only slightly
bigger or same size as human palm. Therefore, handwriting recognition is
a very attractive input method.
The most prominent problem
in handwriting recognition is the vast variation in personal writing styles.
A recognition system should be insensitive with minor variations and still
be able to distinguish different but sometimes very similar looking characters.
Recognition systems should, at least in the beginning, be able to recognise
many writing styles. Such multi-user systems usually have problems with
recognition accuracy. One way to increase performance is adaptation, which
means that the system learns its user's personal writing style.
The main goals of the master's
thesis Adaptation in On-line Recognition of Handwriting were to make a
literature survey of the state-of-art recognition methods and to develop
adaptive methods for on-line recognition of isolated
hand-written characters. The experiments reported in the work showed that
with the suggested adaptation methods, recognition accuracy high enough
to be acceptable for a real-world application could be attained for most
of the writers.
The work described in the
thesis has been carried out in co-operation with Nokia Research Center.
The Technology Development Centre Finland (TEKES) as part of the technology
programme Adaptive and Intelligent Systems Applications have funded it.
