20.500.12556/RUL-110529 Sledenje očem z uporabo spletne kamere Eye-tracking with a web camera V diplomski nalogi se soočimo s problemom napovedovanja točke pogleda z uporabo spletne kamere za potrebe aplikacije za zaznavo disleksije. Specifični primer uporabe nam omogoča dodatne omejitve problema. V osnovi je problem razdeljen na dva dela. Prvi del rešimo z metodami računalniškega vida in vključuje zaznavo obraza, interesnih točk in središča zenice. V drugem delu z uporabo globoke nevronske mreže napovemo točko pogleda. Z opravljenimi eksperimenti definiramo parametre kalibracije. V najboljšem primeru smo dobili povprečno napako napovedi v radiju 3,37 cm. To nam pogojno omogoča uporabo predstavljenega pristopa za potrebe aplikacije. We consider a problem of gaze prediction using a simple webcam for use with an application that screens for dyslexia. The specific use case enables us to define additional boundaries that simplify our problem. On a higher level the problem is composed of two sub problems. The first one requires us to detect the users face, find its landmarks and in the end locate the eye center. We solve this as a computer vision problem. The second sub problem is mapping the features to a point on the screen. For this we used a deep neural network. For optimal results we preform experiments on how to most efficiently calibrate. In the best test case we were able to achieve an average of 3,37 cm prediction error. This puts our approach at most conditionally suitable for use with the target application. računalnik oči sledenje kamera computer eyes tracking webcam true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-09-16 13:10:12 2019-09-16 13:10:15 2022-08-22 03:44:20 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 23893 1538347459 Vranjes_Luka_-_Sledenje_ocem_z_uporabo_spletne_kamere.pdf Vranjes_Luka_-_Sledenje_ocem_z_uporabo_spletne_kamere.pdf 1 F3B8076D67194A0D6975821A8F14D267 0a87a082c090ffaef83dd306e19c41ec7cbdf803c1df8d9600d7f642c2a498d4 244a043b-a1b7-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=122199 Fakulteta za računalništvo in informatiko 0 0 0
