Video object level time domain editing method and system

The invention discloses a video object level time domain editing method and a video object level time domain editing system, and relates to the technical field of video processing. The method comprises the following steps of: S1, extracting a static background image of each frame in video; S2, subtracting the corresponding static background image from an image of each frame in video to acquire a video object; S3, adjusting the initial playing time of the video objects, and setting re-sampling modes of the video objects; S4, selecting the initial playing time and the re-sampling mode of the video objects, and rearranging the video objects on the time domain according to the selection result; and S5, synthesizing the image of each frame of the rearranged video objects and the corresponding static background image so as to acquire a video editing result. By acquiring the static background images, labeling and acquisition of the video objects can be realized without using a fine segmentation mode, the time domain editing of single video object level is quickly realized, and various specific video effects are achieved.
