Patent ID: 7375731

Claim:
A method for mining content of a sequence of frames of a video, comprising: selecting a low-level feature of the content of the sequence of frames of the video; generating time-series data from the content of the sequence of frames of the video, the time series data comprising the selected low-level feature; implicitly constructing windows for the time-series data, in which the windows are multi-resolution, a distance D between two windows of size w at points x i and x i in the time series data is measured as D w ⁡ ( x i , x j ) = ∑ k = 0 w - 1 ⁢ ( x i + k - x j + k ) 2 , and k is an index for the points x i and x j in the windows; self-correlating the time-series data, using the multi-resolution windows, to determine similar segments of the sequence of frames of the video according to the low-level feature, and wherein all similar segments are found at a plurality of temporal resolutions; and clustering the similar segments to discover high-level patterns in the content of the sequence of frames of the video.
