When you are trying to reshape it using test_img2 = test_img2.view (1, 3, H, W) it mixes all the values, instead of just swapping the dimensions. WebThe FlowNet demonstrated that optical flow estimation can be cast as a learning problem. However, the state of the art with regard to the quality of the flow has still been defined by traditional methods. Particularly on small displacements and real-world data, FlowNet cannot compete with variational methods.

The idea is that this class get a list of filename tuples (curr image, next image) containing the current and next frame filenames of the video sequence instead of simple filename list. This allows to get the correct image pairs after suffling the filename list.
