Problems solved by technology

[0003] In the video conferencing application process, in order to avoid the leakage of the user's personal privacy, you can choose to use the virtual background to replace the real environment background. Zoom out, etc.), resulting in the separation of the focused foreground object from the virtual background, making the image presented on the video conference interface unnatural, and reducing the experience of using the virtual background

Embodiment Construction

[0046] Description of the Background section for, in order to enable the background virtual video conferencing configuration, synchronization can be adjusted as a foreground object (e.g., user) photographed will change, and the virtual background and the foreground object such that the focus can be more natural fusion , to watch from the visual user experience of the foreground object is located in the virtual background.

[0047] Based on this, the present application proposes a number of adjacent captured by a video frame is analyzed to determine a current video frame with respect to the moving foreground object parameters for the history of the video frame, such as the user moves around with respect to the image capture device, move forward and backward rotation, because users often fixed in their environment, which results in a relatively fixed position of the user's changes in the real background acquired corresponding video frames in order to improve the image quality of a v...

Abstract

The invention provides a video virtual background image processing method, a video virtual background image processing device and computer equipment. In order to protect personal privacy, in a video conference scene displayed after a virtual background image is configured to replace a real background image in a real video stream, the computer equipment receives a trigger instruction, a first video frame in the real video stream and a historical video frame adjacent to the first video frame or spaced by a specific number of frames from the first video frame can be obtained, the moving parameter of the foreground object of the first video frame relative to the historical video frame is analyzed, and therefore synchronous adjustment of the virtual background image presented by the video interface is achieved according to the moving parameter. The fusion of the adjusted virtual background image and the foreground object is more natural, and the use feeling of using the virtual background in the video conference is improved.

Description

Technical field [0001] The present application relates to a technical field of image processing, and more particularly to a virtual background video image processing method, apparatus and computer equipment. Background technique [0002] With the development of multimedia technology and artificial intelligence, multi-party video call has been applied to all areas of work, education and medical care, the rapid increase in the demand for applications in various fields multi-line remote communication scenes, making video conferencing has become an important productivity tool. [0003] In the video conferencing application process, in order to avoid the user's personal privacy is compromised, you can choose to use a virtual background replace real environmental context, however, were in the process of focusing the camera, the display will change the status of captured foreground object (such as zoom in / narrow etc.), leading to the virtual focus foreground objects separated from the...
