Could please explain at length what the warp does in your paper? I do not the specific operation. Thanks

The warp on the 3D probability volume is for the step that corresponds to the prediction in the Kalman Filter. It estimate the volume at time t+1, given the volume at time t, without using the image at time t+1. This is done as the resampling operation in the code
