Abstract:V diplomski nalogi smo naredili program za kodiranje videa v video format z indeksnimi barvami. Seznanili smo se z več načini tvorbe optimirane barvne palete in jih vključili v implementacijo. Za samo stiskanje videa, reduciranega na barve iz palete, smo opcijsko uporabili algoritem LZW. Opcijsko smo vključili tudi preprosto kriterijsko funkcijo, ki ob vsakem video okvirju odloča, ali se bo uporabila paleta prejšnjega okvirja ali pa se bo določila na novo. Opisali smo vse implementirane algoritme ter prikazali rezultate.

Title:INDEXED-COLOUR-BASED DIGITAL VIDEO
Abstract:In the diploma work we built a program for coding video into a data format with indexed colours. We studied different quantization algorithms for optimized colour palette creation, and implemented them. Video reduced to colours from the palette can be optionally compressed by LZW algorithm. We have also incorporated a simple criterion function, which decides at each video frame whether to employ the palette from the previous frame or to determine a new one. We described all implemented algorithms and displayed the results.
Keywords:video coding, indexed colours, video with quantization algorithm, video compression, LZW
