The embodiment of the invention provides a compensation frame generation method and device, and the method comprises the steps: obtaining a first video frame and a second video frame, determining a first region in the second video frame, wherein the first region and a target region in the first video frame meet a preset image feature similarity condition, and determining a second region, wherein the second region and the target region meet a preset pixel value similarity condition; determining a first relative displacement between the target area and the first area, and determining a second relative displacement between the target area and the second area; based on the first relative displacement and the second relative displacement, determining a target relative displacement of the image content contained in the target area; and generating compensation frames of the first video frame and the second video frame based on the target relative displacement. By applying the scheme provided by the embodiment of the invention, the quality of the generated compensation frame can be improved.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a compensation frame generation method and device. Background technique [0002] In order to increase the frame rate of the video, video frame insertion can be performed on the video. Video frame insertion refers to inserting a new video frame between two video frames, and the inserted video frame has a strong content correlation with the two video frames, so as to ensure the smoothness of the video content. A frame may also be referred to as a compensation frame. In the prior art, during video frame interpolation, problems such as texture anomalies and dislocations usually occur in the generated compensation frames, especially for high-speed motion videos, the generated compensation frames display abnormalities more obviously. Therefore, there is an urgent need for a compensation frame generation method to improve the quality of the generated compensation fram...
