20.500.12556/RUL-103815 Avtomatska segmentacija belih madežev na gladkih zobnih ploskvah Automatic segmentation of white spot lesions on smooth tooth surfaces Vse pogosteje se za medicinske namene uporablja računalniške tehnologije, saj te predstavljajo pomemben gradnik sodobnega zdravstva. Po snetju nesnemljivega ortodontskega aparata se pogosto pojavijo začetki demineralizacije, ki se kažejo kot bele ploskve na gladkih površinah zobne sklenine. V magistrskem delu razvijemo prototip sistema za avtomatsko segmentacijo zob in belih madežev, ki lahko pripomore k bolj natančnemu in objektivnemu spremljanju zdravljenja. Pri razvoju smo uporabili različne tehnike za obdelavo slik in algoritmov za segmentacijo. Razvit sistem smo ovrednotili na podatkovni zbirki, katero smo pripravili iz izbranih slik kliničnih pregledov. Rezultati so pokazali, da sistem deluje in ima še veliko prostora za nadaljnje delo ter izboljšave. Computer technologies are ubiquitous and in the recent times, these technologies are penetrating more into the field of medicine, where they play a vital role in modern healthcare. In this master's thesis, we are solving a problem, which dentists typically encounter during teeth alignment treatment. At the end of the treatment, when permanent orthodontic braces are removed, the initial phase of tooth demineralization often appears as white spot lesions on the smooth surfaces of a tooth. We developed a prototype for automatic segmentation of teeth and white spot lesions, which may contribute to a more accurate and objective way of treatment monitoring. In the process of development, we used various image processing techniques and image segmentation algorithms. The developed prototype was evaluated against a database, which we built from the selected images of clinical examinations. The prototype showed promising results with a lot of potential for improvements and future work. računalniški vid obdelava slik beli madeži segmentacija slik rast regij segmentacija z grafi computer vision image processing white lesions image segmentation region growing segmentation with graphs true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2018-09-26 15:15:02 2018-09-26 15:15:06 2022-08-17 03:41:44 0000-00-00 00:00:00 2018 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 21062 Kozjek_Klemen_-_Avtomatska_segmentacija_belih_madezev_na_gladkih_zobnih_ploskvah.pdf Kozjek_Klemen_-_Avtomatska_segmentacija_belih_madezev_na_gladkih_zobnih_ploskvah.pdf 1 73ABE17D1DC2E37DA3BE96C023874803 92e64edd8a3619acac361b6c3e68943d77780e34cc89d829149d608a716a6925 e94cf0ab-a1b5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=114315 Fakulteta za računalništvo in informatiko 0 0 0
