Abstract
In a method for training temporal precipitation interpolation models, the method may include receiving an initial image, a first intermediate image, and a final image, computing a first preliminary forward optical flow vector field from the initial image, and a first preliminary backward optical flow vector field, computing a first refined forward optical flow vector field and a first refined backward optical flow vector field using a terrain factor, among other things, and computing backpropagation losses to train neural networks by comparing the first intermediate image to an interpolated frame calculated using the first refined forward optical flow vector field and the first refined backward optical flow vector field.
