Semisupervised segmentation of UHD video

Popis výsledku v původním jazyce

One of the key preprocessing tasks in informa- tion retrieveal from video is the segmentation of the scene, primarily its segmentation into foreground objects and the background. This is actually a classification task, but with the specific property that it is very time consuming and costly to obtain human-labelled training data for classifier training. That suggests to use semisupervised classifiers to this end. The presented work in progress reports the inves- tigation of semisupervised classification methods based on cluster regularization and on fuzzy c-means in connection with the foreground / background segmentation task. To classify as many video frames as possible using only a single human-based frame, the semisupervised classifica- tion is combined with a frequently used keypoint detec- tor based on a combination of a corner detection method with a visual descriptor method. The paper experimentally compares both methods, and for the first of them, also clas- sifiers with different delays between the human-labelled video frame and classifier training.
