Abstract

Algoritam koji je korišten za praćenje igrača je Meanshift algoritam. Taj
algoritam se temelji na računanju težišta čestica u slici koje su dobivene iz
projekcije histograma. Histogrami su izračunati nad slikom koja je u HSV
prostoru boja. Takav prostor boja odabran je jer je otporniji na promjenu
osvjetljenja naspram RGB sustava boja. Cijelo praćenje se može izvesti koristeći
samo jedan histogram terena. Meanshift algoritam radi tako da računa težište
skupa čestica (piksela) te pomiče pravokutnik u kojem se radi računanje težišta.
Programsko rješenje je dokumentirano svojim odgovarajućim uputama za korištenje
i dijagramom stanja i dijagramom razreda koji daju uvid u to kako je rješenje
izvedeno. U ovom radu su prikazani i rezultati koji su također obrađeni u ovom radu.

Abstract (english)

Algorithm which is used for player tracking is Meanshift algoritam. Meanshift
algorithm is based on calculation of particles center of gravity in picture
which is obtained from histogram backprojection. Histograms are calculated from
picture which is converted from RGB to HSV color space. HVS color space is more
resistant to change in brightens as opposed to RGB color space. Whole
player tracking is produced by just one histogram of football pitch. Meanshift
algorithm adjusts tracking bounding box by calculating center of gravity of
particles(pixels). Programming solution is well documented and it has its own
user manual, class diagram and state diagram which is contained in this
document. In this document solution scores and fitness are shown and all
results are analyzed.
