Abstract:
1. 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 and k is an index for the points x 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.
