Abstract
Rushes are the raw materials used to produce a video. They often contain redundant and
repetitive contents. Rushes summarization aims to provide a quick overview for a rushes
video. As part of TRECVID 2007, NIST initiates a rushes summarization task. This paper
reports on the design of NTU rushes summarization system. Our system consists of three
components, shot segmentation, redundant shot detection and summary creation. To tackle
the bulky rushes, we focus on efficient but effective feature representations (i.e. , local color
histograms, compressed-domain motion vectors, etc.) and summarization methods. Besides,
we proposed a novel approach to detect clapper shots which are not only relevant to concise
summarizes but also essential for indexing numerous camera takes in the rushes. Even
practically efficient and requiring only 40% of the video time for computation, the proposed
system achieved satisfying results in TRECIVD 2007 rushes summarization task.
