Video importance rating based on compressed domain video features

摘要

Systems and methods are provided for identifying important video frames and segments in multimedia content such as a segmented compressed domain video. Video frames in a segment are analyzed to determine intensity, contrast, and motion values for the frames and their segments. The values among frames and segments are compared to identify one or more video segments likely to be important to a viewer. The systems and methods may additionally be augmented with audio data other characteristics associated with the video frames and segments analyzed.

主权项

1. A method, comprising:
receiving, at a video frame analyzing device, a segmented video sequence; identifying a first video frame in said segmented video sequence; determining an intensity value for the first video frame; determining a contrast value for the first video frame; determining that the contrast value is less than a predetermined threshold, and based on said determination lowering the intensity value by a predetermined amount, and comparing, by the device, the first video frame to a second video frame in the segmented video sequence, said comparison based on the determined intensity value and the determined contrast value.
