Methods and systems for providing guidance for adjusting a target. For example, a computer-implemented method for providing guidance for adjusting a target includes: receiving, by a neural network, a reference image; receiving, by the neural network, the target image, the target image being related to a position of a target; determining a similarity metric based at least in part on information associated with the reference image and information associated with the target image by the neural network; generating a target attention map corresponding to the target image based at least in part on the similarity metric; outputting the target image and the target attention map; and providing a guidance for adjusting the position of the target based at least in part on the target image and the target attention map.
