Szukana fraza: [Abstract = "As a result of research two related algorithms of video segmentation were developed, however, each of them fulfill different assumptions and perform segmentation in a different way. The first algorithm separates foreground objects from a background in two steps and can be applied to a wide class of video sequences. The first step of the algorithm uses Fast Marching Method to perform initial segmentation while the second step improves segmentation quality. The second algorithm developed in this thesis is able to segment a video sequence into many separate objects but is limited to the sequences containing only rigid objects that perform only translational motion. In the latter case, the multilabel version of the Fast Marching Method was used."]
