The paper proposes an approach for unauthorized inter-frame video change detection using spatio-temporal slices. This approach can significantly reduce the amount of data processed and replace video processing with image processing that could be performed much faster. To test the efficiency of this approach, we consider a simple algorithm in analyzing adjacent rows of a slice and then classifying the rows based on its result. Experimental studies have revealed that this algorithm shows moderate results in terms of quality, but it has a great potential for improvement, which confirms the prospects of spatio-temporal slices for the given problem.
