By contrast, we are able to predict the orientation and other variables independently, and yet more effectively, with a novel dual-branch regression network, based on the observation that the ship targets are nearly rotation-invariant in remote sensing images.

A cyclic iteration process is then proposed to extract the background from the discriminative frame set.
