Embodiment Construction

[0022] The object of video information extraction in the present invention can be a participant of a conference or a lecturer of an open class. For the convenience of understanding, a detailed specific implementation is given in conjunction with the video information extraction of the lecturer.

[0023] Such as figure 1 Shown, a kind of video extraction method comprises steps:

[0024] Step S110, collecting the desktop video image and setting a time stamp, obtaining the desktop video image and the composite video image as the extraction target of the extraction object, and setting a time stamp on the composite video image at the same time; the desktop video image is the extraction target background video image; in the present embodiment, camera is used to obtain the desktop video image and the composite video image as the extraction target of the extraction object, and the corresponding time stamp is set to facilitate the adjustment of the parameters of the collected video ima...

Abstract

The invention discloses a video extracting method. The method includes steps of collecting a desktop video image, setting timestamp, acquiring a composite video image of the desktop video image and an extraction target which is used as an extraction object, and simultaneously, setting timestamp of the composite video image, wherein the desktop video image is a background video image of the extraction target; adjusting a resolution ratio to enable a required resolution ratio of the composite video image to be same as a resolution ratio of the desktop video image, positioning the desktop video image and the composite video image, and adjusting video parameters to be identical according to the timestamp of the images; and subjecting the large screen desktop video image and the composite video image to frame comparison according to the timestamp, and extracting the video image of the extraction target in the composite video image. The invention further discloses a video extracting device. The method and the device are used for extracting the video images, the operation is simpler, and the extracted video images are clearer.

Description

technical field [0001] The invention relates to the field of video communication, in particular to a video extraction method and device. Background technique [0002] Video target extraction technology can extract video images of moving targets against a still background. [0003] The general video target extraction method is to extract the target as an object or a video layer. The calculation is more complicated, such as: human figure comparison library, face comparison library, etc., and the calculation amount is large, which is difficult for moving backgrounds. The extraction effect is not ideal, and there are obvious problems such as edge jaggedness. [0004] When the extraction target is extracted as an object or a video layer, when the video of the extraction target is merged with the desktop video again, there will also be blurred fusion edges or obvious edge jaggedness; Contents of the invention [0005] Based on this, it is necessary to provide a video extractio...
