We propose a new effective shape descriptor, chord context, for shape description in content-based image retrieval. For a shape, the chord context describes a frequency distribution of chord lengths with different orientations. The histograms which represent the chord context are compacted and normalized into a feature matrix. Unlike other shape representation schemes, the proposed scheme is able...
This paper proposes a new approach for shot boundary detection using information saliency. Both temporal and spatial saliency are considered to generate an information saliency map (ISM). The shot detection (both abrupt changes and gradual transitions) is then based on the change of saliency, Six publicly available video databases are used for evaluation and the results are encouraging. The overall...
