The Traditional Setting for Optical Flow
In optical flow, we have multiple frames. And for each pixel, we want to find where the pixel was in the previous frame or from previous frame, where it moved in the current frame. So this is kind of a high level AI base motion estimation that I mentioned. We are training models taking multiple images and then network applies a feature extractor around each pixel. It tries to learn most representative, useful information through convolutional kernels.
