The fmt step of video retrieval is the shot change detection, which segments a video into temporal shots and makes the retrieval possible. A new effective algorithm for video's abrupt shot change detection, called twi-difference algorithm, is proposed in the paper. This method eliminates the influence of video movement on the abrupt shot change detection and improves the detecting performance greatly without additional computational cost. And it is based on the property of the inter-frame difference of the fkxnes at the video movement, and is sequence-independent. Experiments show that the twi-difference algorithm outperforms the inter-frame difference algorithm greatly, and the pixel-matching twi-difference algorithm realizes the no-missing detection with close-to-zero or few false detection for the abrupt shot change.Index Termsabrupt shot change detection; twi-difference algorithm, pixel-matching twi-difference algorithm
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
