Abstract
Video information defining video content may be accessed. The video content may include video frames. Motion vectors for the video frames may be determined. The motion vectors may represent motion of one or more visuals captured within individual video frames. A transformation matrix for the video frames may be determined based on the motion vectors. The transformation matrix may characterize rigid transformations between pairs of the video frames. Shakiness metrics for the video frames may be determined based on the transformation matrix. A shakiness threshold may be obtained. One or more of the video frames may be identified based on the shakiness metrics, the shakiness threshold, and algorithms with hysteresis or finite-state machines. A video summary of the video content may be generated. The video summary may include the one or more identified video frames.
