摘要： A device, system and method for online video condensation are provided. The method comprises: step 1, obtaining a frame of image; step 2, segmenting a foreground image and a background image from the image, and carrying out step 3 on the segmented foreground image, and carrying out step 5 on the segmented background image; step 3, extracting moving objects from the foreground image; step 4, circularly executing step 1 to step 3, and cumulating the moving objects respectively extracted from each frame of foreground image to form a moving object sequence until the number of cycles reaching a predetermined value; step 5, circularly executing step 1 to step 2, and cumulating the background image of each frame of image and extracting n frames of specific background images as a main background sequence until the number of cycles reaching a predetermined value; step 6, mosaicking the main background sequence and the moving object sequence to form a condensation video. The method utilizes an online condensation mode, and shortens the length of the condensation video and retains the information of the moving objects of the video as much as possible.
