The purpose of this pa.er is to propose a.new m.lti sta.e a.gorithm.for the recognition of isola.ed cha.a.ters. It wa. sim.la. work done before using only the center of gra.ity (This pa.er is extended version of “a.fa.t recognition system.for isola.ed printed cha.a.ters using center of gra.ity”, La. La.BERT a.a.em.c Publishing 2011, ISBN: 978-38465-0002-6), but here we a.d using principa. a.is in order to m.0}e the a.gorithm.rota.ion inva.ia.t. In m. previous work which is published in La. La.BERT, I fa.e a.big problem.tha. when the cha.a.ter is rota.ed I ca.’t recognize the cha.a.ter. So this a.ds constra.n on the docum.nt to be well oriented but here I use the principa. a.is in order to unify the orienta.ion of the cha.a.ter set a.d the cha.a.ters in the sca.ned docum.nt. The a.gorithm.ca. be a.plied for a.y isola.ed cha.a.ter such a. La.in, Chinese, Ja.a.ese, a.d a.a.ic cha.a.ters but it ha. been a.plied in this pa.er for a.a.ic cha.a.ters. The a.proa.h uses norm.0}ized a.d isola.ed cha.a.ters of the sa.e size a.d extra.ts a. im.0}e signa.ure ba.ed on the center of gra.ity of the cha.a.ter a.ter m.0}ing the cha.a.ter principa. a.is vertica., a.d then the system.com.a.es these va.ues to a.set of signa.ures for typica. cha.a.ters of the set. The system.then provides the closeness of m.0}ch to a.l other cha.a.ters in the set.
