Blind summarization of video content
First Claim
Patent Images
1. A method for summarizing unknown content of a video, comprising:
- selecting low-level features of the video;
partitioning the video into segments according to the low-level features;
generating time-series data from the video based on the selected low-level features of the video;
self-correlating the time-series data to determine the similar segmentsgrouping the segments into a plurality of disjoint clusters, each cluster containing similar segments;
labeling the plurality of clusters with labels according to the low-level features;
finding high-level patterns among the labels; and
extracting frames from the video according to the high-level patterns to form a content-adaptive summary of the unknown content of the video.

Abstract
A method summarizes unknown content of a video. First, low-level features of the video are selected. The video is then partitioned into segments according to the low-level features. The segments are grouped into disjoint clusters where each cluster contains similar segments. The clusters are labeled according to the low-level features, and parameters characterizing the clusters are assigned. High-level patterns among the labels are found, and the these patterns are used to extract frames from the video according to form a content-adaptive summary of the unknown content of the video.
