摘要
A compact image sequence descriptor (101), used for describing an image sequence, comprises a segment global descriptor (113) for at least one segment within the sequence, which includes global descriptor information for respective images, relating to interest points within the video content of the images. The segment global descriptor (113) includes a base descriptor (121), which is a global descriptor associated with a representative frame (120) of the image sequence, and a number of relative descriptors (125). The relative descriptors contain information of a respective global descriptor relative to the base descriptor allowing to reconstruct an exact or approximated global descriptor associated with a respective image of the image sequence. The image sequence descriptor (101) may further include a segment local descriptor (114) for a segment, comprising a set of encoded local feature descriptors.
