Abstract: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.
Keywords:računalniška geometrija, verižne kode, vokselski model, ogliščna verižna koda, Freemanova verižna koda, triortogonalna verižna koda

Title:CAHIN CODES OF GEOMETRIC OBJECTS REPRESENTED BY VOXELS
Abstract: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.
Keywords:computational geometry, chain code, voxel model, vertex chain code, Freeman chain code, three orthogonal symbol chain code
