To Recognize Bold Printed Numerical Characters with Shape Variation by Using Fuzzy Statistic Method
Affected by the wearing of frequent usage and variation of environmental brightness
binaried numerical character images of freight train become deformed and incompleted
which are sampled by freight train mark recognizing system under various weather conditions. As traditional methods
for example pattern plate matching
are not effective to extract the character features exactly
a new method called fuzzy-statistic is presented according to which the numerical character' s figure features inside and outside them are extracted by computing their direction routes. By the mean time the fuzzy decision method is drawn on to overcome the indefiniteness during feature extracting. After utilize in some power plant
it appeared that the method is available for character's deformed and incompleted
also high recognized-rate was obtained. The method might be referred to recognize bold printed numerical characters and other courses.
