Discriminative techniques for keyframe selection
ICME(2005)
摘要
A convenient representation of a video segment is a sin- gle "keyframe." Keyframes are widely used in applications such as non-linear browsing and video editing. With exist- ing methods of keyframe selection, similar video segments result in very similar keyframes, with the drawback that ac- tual differences between the segments may be obscured. We present methods for keyframe selection based on two crite- ria: capturing the similarity to the represented segment, and preserving the differences from other segment keyframes, so that different segments will have visually distinct repre- sentations. We present two discriminative keyframe selec- tion methods, and an example of experimental results.
