Video frame insertion method and device, training method and device, electronic equipment and storage medium

The invention discloses a video frame insertion method and device, a training method and device, electronic equipment and a storage medium, and relates to the technical field of computer video processing.The training method comprises the steps that firstly, a global space-time dependency relationship between two input video frames is established through a non-local neural network, and a first frame feature map and a third frame feature map are obtained; secondly, generating a rough middle frame feature map from the first frame feature map and the third frame feature map through an adaptive fusion module so as to eliminate space-time redundant information generated by a non-local neural network; then, deformable convolution is carried out on the rough intermediate frame feature map to obtain an accurate intermediate frame feature map, and errors are reduced in a self-reference mode; and finally, inputting the accurate intermediate frame feature map into a reconstruction network to generate an intermediate fram
