Optical braille recognition

Optical Braille Recognition ni tekinoroji yo gufata no gutunganya amashusho ndetse n'inyuguti ya brile  karemano . Ikoreshwa muguhindura inyandiko za braille kubantu badashobora kuyisoma mumyandiko, no kubungabunga no kubyara inyandiko.

 Amateka 
Mu mwaka wa 1984, itsinda ry’abashakashatsi bo muri kaminuza y’ikoranabuhanga ya Delft ryateguye igisate cyo gusoma cyo mu bwoko bwa braille, aho umutwe wo gusoma ufite selile zifotora zimuriwe hamwe n’abategetsi kugira ngo bafate inyandiko y’inyandiko umurongo ku murongo ubu buryo kandi bufasha cyane abafite ubumuga bwo kutabona.  Mu 1988, itsinda ry’abashakashatsi b’Abafaransa muri kaminuza y’ubumenyi n’ikoranabuhanga ya Lille bakoze algorithm, yitwa Lectobraille, yahinduye inyandiko za brile mu nyandiko isanzwe. Sisitemu yafotoye inyandiko ya braille hamwe na kamera ntoya ya CCD, kandi ikoresha tekinoroji yo kuyungurura umwanya, kuyungurura hagati, isuri, no kwaguka kugirango ikuremo braille. Inyuguti za braille zahinduwe mururimi karemano hakoreshejwe kumenyekanisha imiterere . Tekinike  yari ifite ikosa rya 1%, kandi ifata igihe cyo gutunganya amasegonda arindwi kumurongo.  Mu mwaka wa 1993, itsinda ryabashakashatsi bo muri Katholieke Universiteit Leuven ryashyizeho uburyo bwo kumenya braille yari yarabisikanye hamwe na scaneri iboneka mubucuruzi.  ariko, ntabwo yashoboye gukemura ikibazo cyubumuga buri muri gride ya braille, kubwibyo byasabwaga ibyangombwa bya braille byakozwe neza.  Mu 1999, itsinda ryo muri kaminuza ya Hong Kong Polytechnic ryashyize mu bikorwa tekinike yo kumenyekanisha ku bafite ibumuga bwo kutabona ikoresheje impande zombi kugira ngo ihindure braille mu nyandiko y'Icyongereza cyangwa Igishinwa.  Mu 2001, Murray na Dais bakoze sisitemu yo kumenyekanisha intoki, isikana ibice bito byinyandiko icyarimwe.  Kubera agace gato kasikiwe icyarimwe, guhindura gride ntabwo byari ikibazo, kandi hakoreshejwe algorithm yoroshye, ikora neza.  Mu 2003, Morgavi na Morando bakoze sisitemu yo kumenya inyuguti za braille bakoresheje imiyoboro yubukorikori . Sisitemu yari izwiho ubushobozi bwo gukemura ibibazo bitesha agaciro kurusha ubundi buryo. 

 Inzitizi 
Byinshi mubibazo byo gutunganya neza inyandiko ya braille bituruka kumiterere yinyandiko za braille. Ubusanzwe Braille yacapishijwe kumpapuro zikomeye, ndetse na wino itanga itandukaniro hagati yinyuguti yazamuye nimpapuro zinyuma. Ariko, ubusembwa kurupapuro bushobora kugaragara muri scan cyangwa ishusho yurupapuro.

Inyandiko nyinshi zacapishijwe inter-point, bivuze ko zifite impande ebyiri. Nkibyo, kwiheba kwa braille kuruhande rumwe bigaragara ko bifatanye hamwe na braille igaragara kurundi ruhande ibi bigafasha cyane abafite ubumuga bwo kutabona kuko biborohera cyane mugusoma izini nyandiko za Braille. 

 Ubuhanga 
Bumwe mu buryo bwa optique bwo kumenyekanisha braille bugerageza gukoresha amatara ya oblique na kamera kugirango igaragaze igicucu cya depression no gusohoka kwa braille. Abandi bakoresha ibikoresho biboneka mubucuruzi. Antonacopoulos, A.; Bridson, D. (2004). "A Robust Braille Recognition System". Document Analysis Systems. Lecture Notes in Computer Science.
