Title: VERIŽNE KODE GEOMETRIJSKIH OBJEKTOV PREDSTAVLJENIH Z VOKSLI Bračun, Rok (Author)Žalik, Borut (Mentor) More about this mentor... Lukač, Niko (Co-mentor) UNI_Bracun_Rok_2013.pdf (1,48 MB) Slovenian Bachelor thesis/paper (mb11) 2.11 - Undergraduate Thesis FERI - Faculty of Electrical Engineering and Computer Science Verižne kode se uporabljajo za opis oblike digitaliziranega objekta v 2D ali 3D prostoru. Algoritmi, ki jih generirajo, se razlikujejo v naboru simbolov, ki jih uporabljajo. Verižne kode generiramo tako, da premike zakodiramo s simboli, ki jih določi algoritem. Implementirali smo tri algoritme: 8-smerno Freemanovo kodo, ogliščno verižno kodo in triortogonalno verižno kodo. Pri prikazu 3D objekta na večji mreži je najboljše rezultate dosegla 8-smerna Freemanova verižna koda, pri manjših mrežah pa sta se najbolje odrezala ogliščna verižna koda in triortogonalna verižna koda. računalniška geometrija, verižne kode, vokselski model, ogliščna verižna koda, Freemanova verižna koda, triortogonalna verižna koda 2013 [R.

Language: English CAHIN CODES OF GEOMETRIC OBJECTS REPRESENTED BY VOXELS Chain codes are used to describe a shape of a digitalized object in 2D or 3D space. Algorithms that generate them use different symbols to represent individual codes. To generate a chain code, every step is coded with a corresponding symbol that is set by the algorithm. Three algorithms have been implemented: Freeman chain code of 8 directions, vertex chain code, and three orthogonal chain code. Freeman chain code of 8 directions gave better results when larger scale models are considered. Vertex chain code and three orthogonal chain code turned out better at smaller objects. computational geometry, chain code, voxel model, vertex chain code, Freeman chain code, three orthogonal symbol chain code
