Ugotavljanje podobnosti rastrskih slik z vgnezdenimi 3D izbočenimi lupinami
Žiga Pečar, Borut Žalik, Aljaž Jeromel
Diplomsko delo
Oznake: algoritmi;računalniška geometrija;hitra izbočena lupina;zaznava robov;sivinske slike;diplomske naloge;
V diplomskem delu smo izdelali metodo, ki s pomočjo 3D vgnezdenih izbočenih lupin ugotavlja podobnost med slikami. Najprej smo podali opis štirih že znanih metod za ugotavljanje podobnosti slik. Implementirana metoda prejme sivinsko rastrsko sliko, ki jo redči s Sobelovo zaznavo robov in nato sestav ...
