The recovered high-resolution pseudocolour images of “imgb8” image in the Harvard dataset and the difference image at wavelengths 460, 540, and 620 nm: (a) from top to bottom, GT false colour image, and input HSI at wavelengths 460, 540, and 620 nm; (b–f) from top to bottom, the reconstructed colour image and difference image by (b) BSR [23], (c) CSU [10], (d) NSSR [5], (e) uSDN [20], and (f) ours.
