1. A method for creating a summary of an audiovisual presentation, comprising method operations of:
- segmenting a frame of the audiovisual presentation;
identifying a slide region of the segmented frame;
generating a histogram representing lines in the slide region; and
suppressing moving regions associated with successive frames from the histogram, the suppressing including,assigning a foreground silhouette a most recent timestamp; and
generating a motion mask, wherein edges located within the motion mask are excluded from the histogram.

Abstract
A method for creating a summary of an audiovisual presentation initiates with segmenting a frame of the audiovisual presentation. Then, a slide region of the segmented frame is identified. Next, a histogram representing lines in the slide region is generated. Next, moving regions associated with successive frames from the histogram are suppressed. A computer readable medium, a system for providing a real time summarization of a meeting and an integrated circuit are also provided.

14. A method for creating a summary of an audiovisual presentation, comprising method operations of:
-
segmenting a frame of the audiovisual presentation, the segmenting including; comparing each pixel value of the frame with a plurality of neighbor pixel values, the plurality of neighbor pixel values including pixel values from the frame and from a previous frame; identifying a slide region of the segmented frame; generating a histogram representing lines in the slide region; and suppressing moving regions associated with successive frames from the histogram; the suppressing including, capturing a foreground silhouette;
copying the foreground silhouette;
assigning the copied foreground silhouette a most recent timestamp; and
generating a motion mask, wherein the edges located within the motion mask are excluded from the histogram. - View Dependent Claims (15)
