In this work we present an overview of several methods that extract information from a video segment using pixel-wise histograms or pixel-wise probability distributions. We will show that most of these algorithms that have been presented in the literature are specific implementations of a more general approach. Finally, we will present some applications based on these ideas to video segment retrieval and target detection in surveillance applications with static and dynamic backgrounds. We present a visual segment descriptor based on pixel-wise histograms that outperforms similar reviewed methods. In this way we show the advantages on this approach for this kind of problems.
