Application No. 09/866,394
keyframe images for each superhistogram to create a compact visual summary of the video
material. According to the disclosed and claimed invention, the representative images include at
least one of (1) the first image in each family histogram, (2) the most meaningful image in each
superhistogram, (3) a randomly chosen image, and (4) an image that is closest to the cluster
center.
Claim 1 is illustrative of the claimed invention, and it reads as follows:
1. For use in a system (100) capable of creating visual summaries of video material, an
apparatus (130, 200) for creating a compact visual summary of video material, said apparatus
(130, 200) comprising:
a visual summary controller (130, 200) capable of receiving keyframes of said video
material;
wherein said visual summary controller (130, 200) is capable of extracting frame
signatures from said keyframes, and capable of using said frame signatures to create
superhistograms from said keyframes, and capable of using said frame signatures and said
superhistograms to select representative keyframe images for each superhistogram to create a
compact visual summary of said video material,
wherein said representative images include at least one of (1) the first image in each
family histogram, (2) the most meaningful image in each superhistogram, (3) a randomly chosen
image, and (4) an image that is closest to the cluster center.
