METHOD AND SYSTEM FOR SPLITTING AND COMBINING IMAGES FROM STEERABLE CAMERA

摘要

The present invention provides a method for processing a video stream taken by a steerable camera to segment the same. The method comprises converting the video stream into an image sequence; segmenting each image of the image sequence to extract a foreground image and a background image; combining background images of the image sequence to form a global map; determining motion frequency of the foreground image through a motion table, wherein the motion table has a same (pixel?) size as the global map, each cell of the motion table records a count on the a number of foreground images; augmenting the count on the motion table based on the corresponding position of the foreground image over the global map to indicate a high motion area and a low motion area through the number of count; generating a set of local maps of the same size for each motion area over the global map, each local map is incorporated with the corresponding foreground image and its timestamp; and rendering a new segmented video by combing each set of local maps.
