Abstract: Highlights•PDFSR alleviates the conflict between contour reconstruction and detail reconstruction.•A three-level index is proposed for constructing a bias-robust lightweight knowledge base.•A constraint module is proposed to constrain the output of the knowledge base, which reduces the prior error.
