Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] FIG. 1 shows a flowchart of a method for video editing according to the present invention.

[0040] During the shooting of motion video, the motion of the camera will cause the motion of the background of the video image, and this type of motion is called global motion. The local motion corresponds to the global motion, and the local motion refers to the foreground motion caused by the motion of the moving object. Considering that the moving object can be a rigid body or a non-rigid body, the frame difference method based on the time domain is used for the initial segmentation. The frame difference method is based on the assumption that the background is stationary or has a uniform global motion, while the moving objects have properties different from this global motion. In the case that the background has a uniform global mo...

Abstract

The present invention discloses a video editing method based on concatenation of panoramagram, being used for editing or repairing section series of motion video. The method includes the steps as follows: matching with the characteristic point of the every frame image of the video series, calculating the projection matrix between the frames and appending the image to acquire the video panoragram; editing the video panoragram with the human interaction and computer according to the specific demand of video editing; restoring the video series from the edited panoragram based on the projection relationship. Applying the video panoragram as the medium, the present invention shifts the video editing into the image editing of vider panoragram, not only directly providing the whole scene message to the user, but also reducing the calculating quantity and the human interaction.

Description

technical field [0001] The invention relates to a video sequence processing method, in particular to a new method for replacing traditional video editing with image editing of the panorama by synthesizing video panoramas. Background technique [0002] In traditional video editing, videotapes are usually used as the storage medium for lens shooting and editing. Since the materials are stored sequentially on the videotapes, it is necessary to search and copy repeatedly to complete the editing, and rearrange these materials on another videotape. This editing method It is called the linear editing method. Since the development of digital technology, a dedicated non-linear editing machine has appeared, which can be more conveniently processed without following the linear position of the material on the tape. In fact, the PC can also be used as a non-linear editing machine, because all the material is captured to disk, and can be processed at any time in any timeline position. ...
