Used two types of trackers a correlation based and a frequency based tracker, using MMSE and implemented a pre-screener for extracting a set of features in order to track the target when an occlusion is present.
-
The paper presented above implements a correlation based algorithm with very less specifications, our approach includes phase correlation to get the position of the tank faster instead of mean squared error.
-
to improve processing time we also reduced the no.of features to track the centroids faster, in the feature based approach where occlusion was a problem.
