Hi, we use the code "bm = (2 * (bm / 286.8) - 1) * 0.99" rather than "bm = (2 * (bm / 287) - 1)". The goal is to compensate the coordinate bias from the dataset, which would cause the shifting of the rectified image.

did the code "bm = (2 * (bm / 286.8) - 1) * 0.99" use on the pred bm when calculate the BM L1 loss

@lsabrinax It is not used to calculate the flow loss.

@lsabrinax It is not used to calculate the flow loss.

thank you for your reply, does it mean the GeoTr model directly regress the absolute value in flow between 0-287

@lsabrinax Yeah~
