Problems solved by technology

However, in related technologies, the frame interpolation algorithm is implemented by predicting optical flow either explicitly or implicitly, but the accuracy of optical flow detection is low, especially when there are large displacements, occlusions, and complex non-rigid body motions. At the same time, for Transitions, transitions, etc., there is no intermediate state, all of which means that algorithmic frame insertion will bring inevitable flaws
For these defects, manual review requires a lot of manpower, so how to accurately and efficiently detect frame insertion defects has become an urgent problem to be solved
[0003] For the above problems, no effective solution has been proposed

Abstract

The invention discloses a data processing method and device, a storage medium and computer equipment. The method comprises the steps that video data are acquired, the video data comprise a first frame, a second frame and a third frame, and the video data comprise a reference frame; inserting a first intermediate frame between the first frame and the second frame; inserting a second intermediate frame between the second frame and the third frame; inserting a secondary intermediate frame between the first intermediate frame and the second intermediate frame; calculating a difference value between the secondary intermediate frame and the reference frame; and if the difference value satisfies a preset condition, determining the intermediate frame as the target data, the intermediate frame including a first intermediate frame and / or a second intermediate frame. According to the invention, the technical problem of how to accurately and efficiently detect the frame insertion defect in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a data processing method, device, storage medium and computer equipment. Background technique [0002] With the advancement of 5G coverage and large broadband, 4K ultra-high-definition digital media has been vigorously promoted. High frame rate is one of the basic standards of 4K ultra-high-definition video, but a large number of videos in related technologies cannot meet the 4K ultra-high-definition video standard, which includes frame rate. 4K UHD requires a video frame rate of 50 or above, while the frame rate of most existing videos is 25 or 30. In order to solve this problem, it is difficult and time-consuming to do it manually, so it is necessary to use an algorithm to interpolate the video frame. Therefore, in order to convert the existing low-definition video into ultra-high-definition video, algorithmic frame insertion is a necessary step. With the rapid development o...
