IFBlock

2000년 도입 · 논문 6편에서 사용

IFBlock is a video model block used in the IFNet architecture for video frame interpolation. IFBlocks do not contain expensive operators like cost volume or forward warping and use 3 × 3 convolution and deconvolution as building blocks. Each IFBlock has a feed-forward structure consisting of several convolutional layers and an upsampling operator. Except for the layer that outputs the optical flow residuals and the fusion map, PReLU activations are used.
