Abstract

In this paper, a method to determine retake in rushes videos is proposed. This method first divides the video into shots, and then each shot that contains a single color, color bar or clapper board is eliminated. In each remaining shot, the similarity between consecutive frames is calculated using a SIFT matching algorithm and then converted into a string sequence. The similarity between two sequence is evaluated by the Longest Common Subsequence algorithm (LCS). This proposed SIFT - LCS based method was applied to the TRECVID BBC rushes videos of 2007 and 2008 as a competence test. The results support the notion that the proposed method provides a reasonably high degree of accuracy, and identifies the likely causes of poor accuracy for further improvements.
