20.500.12556/DKUM-90655 3D verižne kode F26, F6 in 5OT za opis skeletov vokseliziranih objektov 3D chain codes F26, F6 and 5OT to describe skeletons of voxelised objects V magistrskem delu opišemo tehnike za tvorbo 3D verižnih kod, primernih za opis skeletov vokseliziranih geometrijskih objektov. Osredotočimo se na Freemanovi verižni kodi v 26 in 6 smeri (F26 in F6) ter 5-ortogonalno verižno kodo (5OT). Te verižne kode nato uporabimo za stiskanje 3D skeletov. Verižne kode stisnemo z algoritmi stiskanja RLE, LZW, bzip2 in bzip3 ter primerjamo njihovo uspešnost. Techniques for generating 3D chain codes, suitable for describing skeletons of voxelised geometric objects, are presented in this thesis. We focus on Freeman chain codes in 26 and 6 directions (F26 and F6) as well as the 5-orthogonal chain code (5OT). These chain codes are then used to compress 3D skeletons. The obtained sequences of chain codes are compressed finally with RLE, LZW, bzip2 and bzip3 compression algorithms to evaluate their compression ratio. 3D geometrijski objekti brezizgubno stiskanje podatkov primerjava metod RLE LZW bzip2 in bzip3 3D geometric objects lossless data compression comparison of RLE LZW bzip2 and bzip3 true true false [G.
