Pass in two identical images

Passing two identical images to the network, why the pixel displacement is not 0

Does it work properly on the example images?

It can run normally on the example image, but if two identical images are passed in, the pixel displacement is not 0

Can you give more details about the error? Are the displacements close to zero (<1px), or very large? Is this specific to some data, or it exist for many pairs.

If the error is small, I could image this happening due to dataset bias, considering VCN is still a data-driven method and is not trained on pairs with zero motion. If the error is not negligible, it would be interesting to look into. A way to address this is to add zero-motion pairs to the training data.
