Document Type and Number:
WIPO Patent Application WO/2021/238325
Kind Code:
A1
Abstract:
The present application relates to the technical field of multimedia processing, and provides an image processing method and apparatus, used for solving the problem in the prior art that a special effect video of the motion trajectory of a target filmed object cannot be generated in real time. The method comprises: obtaining a current frame and N historical action frames, wherein the current frame and the N historical action frames respectively comprise a target subject, there is an overlap between the scenario of the current frame and the scenarios of the N historical action frames, and the positions of the target subjects in the scenarios of the N historical action frames are different; performing image segmentation on the N historical action frames to obtain images of the N target subjects respectively corresponding to the N historical action frames; determining N reference positions in the current frame according to the positions of the N target subjects in the scenarios of the N historical action frames and the scenario of the current frame; and respectively fusing the images of the N target subjects to the N reference positions in the current frame to obtain a target frame.
