Seminar about “On Line Pattern Recognition for Handwritten Mathematical Formulas” at Faculty of Computing in Rabigh

Mr.
Mohammad Reyalat presented a seminar about “On Line Pattern Recognition
for Handwritten Mathematical Formulas” in Faculty of Computing and
Information Technology in Rabigh on Monday 30/4/2012 at 12:00 noon.
FCITR faculty members attended the seminar. The following is the brief
of the seminars:
Mr. Mohammad started his seminar by defining the concept of pattern
recognition which is a classification of input data via extracting
important features from a lot of noisy data. After that, the differences
between Online and offline recognition were clarified. On-line
recognition refers to methods and techniques which are dealing with the
automatic processing of a message as it is written, but Off-line case
pertains to scanned images, so it does not deal with the processing of a
message as it is written.
After that, the objective of the study was determined, and some of
necessary background information was presented to attendant to help them
to understand clearly the contents of this study. Then, the proposed
algorithm was explained in details. The first step of this algorithm
includes calculating the slope between each two successive points in the
drawn symbol, the next step includes finding the general specification
for the shape, the next step includes removing the noise from the
obtained data in the previous step, the fourth step includes the process
of feature extraction and the final step includes storing the obtained
features from the previous step into a database.
The techniques of machine learning were implemented heavily in this
study. A lot of difficulties that faced Mr. mohammad during the
implementation of this algorithm were presented to attendant. The fields
of application for this algorithm were discussed at the end of the
seminar.
