Abstract
Systems and methods are provided for optical flow estimation. In one embodiment, a method comprises estimating, with a first neural network, an optical flow between two image frames, wherein a resolution of the optical flow is lower than a resolution of the two image frames, and upsampling, with a second neural network, the optical flow to the resolution of the two image frames. In this way, the speed of optical flow estimation may be improved by reducing the amount of pixels being processed by a deep neural network, while the use of another deep neural network for guided upsampling of the optical flow estimate helps maintain the accuracy of the final output.
