The embodiment of the invention discloses an image processing method and device. Wherein, the method includes: collecting a video image and a depth image of an object; using the depth image to segment the video image frame corresponding to the video image at the same moment, to obtain the outline of the foreground image in the video image frame; according to For the outline of the foreground image, the first encoding is performed on the video image pixels within the outline of the foreground image in the video image frame, and the second encoding is performed on the video image pixels outside the outline in the video image frame. Encoding, obtaining encoded data corresponding to the video image frame, wherein the encoding rate of the first encoding is higher than the encoding rate of the second encoding; outputting the encoded data corresponding to the video image frame and the foreground image The depth data corresponding to the contour. Through the embodiments of the present invention, the network bandwidth occupancy rate in the video image transmission process can be reduced.
Description
technical field [0001] The invention relates to the technical field of image data processing, in particular to an image processing method and device. Background technique [0002] The immersive conference system is a typical next-generation multimedia conference system, which can provide a more realistic and immersive user experience. It usually applies new technologies such as: high-definition audio / video, stereo, 3D video, augmented reality, etc. to allow users to have an immersive experience when participating in meetings. [0003] Generally, an immersive conference system includes two types of cameras, one is a traditional color camera, which can capture a color image of the user; the other is a depth camera, which can capture a depth image of the distance between the user and the camera. Depth information The depth information captured by the camera is of great help to subsequent 3D image synthesis, bone recognition and tracking technologies. [0004] In the existing ...
