  7. Abstract:
  8. In the past few years, virtual advertisement replacement has become one of the most popular methods of advertising. Currently a few companies are applying this novel technique on highly-viewd soccer videos. In the atmosphere of rivalry for achieving a method of cheapest and least needed-equpiment between companies, this thesis is aimed at introducing an all software system based on multi-view soccer videos. The goal is to bring the best possible qualities given the challenges of this particular definition. This thesis provides a system to replace advertisement boards around soccer field which consists of detection, tracking and adjusting the advertisement. In detection the systems aligns the input advertisement placement according to the image observation. For tracking a method is presented based on the previous works of plane tracking trough frames. At the end the proposed system includes a new sub-module named adjustment. This module tries taking accound for frame noise and occlusion via single and multi view informations This systems can perform with moving advertisements, PTZ-only uncalibrated cameras. The system is tested on Azadi data set along with a video released by a advertisement replacement company. The detection module has outputted 62% of 100 random frames from Azadi with correct refinements. Also proposed system is able to track an advertisement 4 times longer than the conventional method with less than 1 pixel error in average. At the end, this system can adjust variety of noises without parameter setting and has proved acceptable in occlusion detection given the challengers of dataset
