Flexible generation of video summaries from layered video bit-streams

The work presented in this paper introduces a method for efficient adaptability of video summaries to spatial requirements defined by display size, user’s needs and channel limitations. By utilising compressed domain features and an efficient contour evolution algorithm, a scale space of temporal video descriptors is generated, enabling dynamic video summarisation in real-time. The summary is laid out utilising an unsupervised robust spectral clustering technique and a fast discrete optimisation algorithm. Results show excellent scalability of the video summarisation interface and highly improved efficiency of summary generation.
