Abstract

The embodiment of the invention discloses a frame insertion image processing method and device. The method comprises the following steps: inputting two reference frames before and after a frame insertion position into an optical flow estimation network to obtain two groups of optical flow fields between a first reference frame and a second reference frame; processing the two groups of optical flowfields by using an optical flow interpolation neural network, and deducing to obtain optical flow data between the two reference frames and a middle frame at the pin position; deducing by using a weight estimation neural network according to the two groups of optical flow fields, the optical flow data and two reference frames to obtain weight distribution for combining the two reference frames; and winding the two reference frames according to the optical flow data, and performing weighted summation on the wound reference frames by using the weight distribution to obtain a target intermediateframe. According to the method, the optical flow data between the reference frame and the intermediate frame can be effectively reconstructed, the stable and reliable intermediate frame can be obtained through combination, and the problems of ghosting, blurring and the like in the frame insertion image are well solved.

Description

technical field [0001] The present application relates to the field of computer image processing, and in particular to a frame interpolation image processing method, device, electronic equipment and storage medium. Background technique [0002] Using the principle of persistence of vision of the optic nerve of the human eye, continuous playback of a series of images can produce smooth and continuous visual effects. Such continuous multi-frame images are called video. Due to the long-term development and evolution of video technology, there are many application scenarios and different technical standards. It is often a problem to convert between various images and / or different video formats. For example, in a video Inserting one or more image frames is one specific requirement. [0003] Frame insertion is usually used to solve the problem of video frame rate to achieve format compatibility or improve the visual experience of playback. Since the inserted image is generally a...
