Embodiment Construction

[0026] Embodiments of the present invention will be described below with reference to the drawings. Elements and features described in one drawing or one embodiment of the present invention may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that representation and description of components and processes that are not related to the present invention and known to those of ordinary skill in the art are omitted from the drawings and descriptions for the sake of clarity.

[0027] Figure 4 A schematic flowchart of a video de-jittering method according to an embodiment of the present invention is shown. Such as Figure 4 As shown, in this embodiment, motion estimation and image synthesis are performed in two rounds. In step S410, as a first round of processing, for each frame in the original video, a transformation matrix for transforming the frame into a shake-removed frame is generated. In step S420, the cropped si...

Abstract

The invention discloses a method and a device for removing video shake. The method for removing the video shake comprises the following steps that: a transformation matrix, which is used for transforming a frame into a shake removed frame, is generated for each frame in an original video; the cutting dimension of the original video is determined; and image synthesis, such as transformation, cutting and expansion, is carried out on each frame in the original video through the transformation matrix of each frame in the original video, the cutting dimension and the resolution ratio of the original video.

Description

technical field [0001] The present invention relates to the technical field of video processing, and more specifically, to a video de-jittering method and a video de-jittering device. Background technique [0002] In recent years, video deshaking systems for removing undesired camera motion (ie, unintentional motion) have become increasingly popular in the consumer market. figure 1 A schematic diagram showing a method of removing jitter in a one-dimensional direction. Such as figure 1 As shown in , the line connected by circles represents the actual movement of the camera, and the line formed by triangles represents the camera movement expected by the photographer, that is, the intentional movement. Intentional motion is motion caused by human intent, for example, an artificial camera movement. The actual motion includes the photographer's intentional motion and unintentional motion. Video de-shaking is to remove the undesired unintentional motion from the actual motion ...
