@hnyll Hi, do you mean that use an existing normal image as prompt/reference? Currently, SAA doesn't support such few-shot mode, but it may be reasonable to calculate the similarity score using PatchCore. Then the similarity score can be used to guide the segmentation process.

@caoyunkang oh wow i didnt know that you would reply so fast.

I'm still kind of new to things related to this field so please correct me where I am wrong.
similarity scores from PatchCore are scores for each patch correct? and these similarity scores is used to segment the parts that are different from the reference and the query?

could you clarify on what you mean by similarity score?
