20.500.12556/DKUM-87036 Implementacija SPIHT magistrsko delo SPIHT implementation V magistrskem delu najprej predstavimo Haarovo transformacijo. Nato razložimo pojme in podatkovne strukture, potrebne za razumevanje algoritma SPIHT. Predstavimo psevdokod implementacije kodiranja in dekodiranja. Delovanje pokažemo na primeru. Algoritem implementiramo in ga testiramo na različnih slikah. Učinkovitost stiskanja primerjamo s formati PNG, JPEG in JPEG 2000, ki se izkaže kot najučinkovitejši. In this thesis, first, the Haar transform is presented. Then, the basic concepts and data structures necessary for understanding the SPIHT algorithm are explained. Pseudocode implementations of encoding and decoding are presented. Their functioning is illustrated with an example. The algorithm is implemented and tested on different images. Compres- sion efficiency is compared with the PNG, JPEG, and JPEG 2000 formats. The most efficient was JPEG 2000.
