Abstract
Abstract A method extracts an intensity of motion activity from shots in a compressed video. The method then uses the intensity of motion activity to segment the video into easy and difficult segments to summarize. Easy to summarize segments are represented by any frames selected from the easy to summarize segments, while a color based summarization process extracts generates sequences of frames from each difficult to summarize segment. The selected and generated frames of each segment in each shot are combined to form the summary of the compressed video.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
A method for summarizing a compressed video including motion and color features, comprising: partitioning the compressed video into a plurality of shots; classifying each frame of each shot according to the motion features, a first class frame having relatively low motion activity and a second class frame having relatively high motion activity; grouping consecutive frames having the same classification into segments; selecting any one or more frames from each segment having the first classification; generating a sequence of frames from each segment having the second classification using the color features; and combining the selected and generated frames of each segment of each shot to form a summary of the compressed video.
Claim 2
Independent Claim
111 words
A method for summarizing a compressed video including motion and color features, comprising: partitioning the compressed video into a plurality of shots; classifying each frame of each shot according to the motion features, a first class frame having relatively low motion activity and a second class frame having relatively high motion activity; grouping consecutive frames having the same classification into segments; selecting any one or more frames from each segment having the first classification; generating a sequence of frames from each segment having the second classification using the color features; and combining the selected and generated frames of each segment of each shot to form a summary of the compressed video.
Claim 3
Dependent Claim
17 words
The method of claim 1 further comprising: combining the selected and generated frames in a temporal order.
Claim 4
Dependent Claim
17 words
The method of claim 1 further comprising: combining the selected and generated frames in a spatial order.
Claim 5
Dependent Claim
19 words
The method of claim 3 further comprising: reducing the selected and generated frames in size to form miniature frames.
Claim 6
Dependent Claim
17 words
The method of claim 1 further comprising: combining the selected and generated frames in a semantic order.
Claim 7
Dependent Claim
43 words
The method of claim 1 further comprising: grouping the frames of each segment having the second classification into clusters according to the color features; generating a cluster summary for each cluster; and combining the cluster summaries to form the generated sequences of frames.
Claim 8
Dependent Claim
14 words
The method of claim 1 wherein the summary is produced while playing the video.
Claim 9
Dependent Claim
14 words
The method of claim 1 wherein the summary is used to resummarize the video.
