Data Preparation

Training dataset

• 7,643 images from the Pascal VOC dataset, center-cropped as 224 x 224 slices to synthesize training pairs;
• 90 real-world training pairs provided by Zhang et al.;
• 200 real-world training pairs provided by IBCLN.

Testing dataset

• 45 real-world testing images from CEILNet dataset;
• 20 real testing pairs provided by Zhang et al.;
• 20 real testing pairs provided by IBCLN;
• 454 real testing pairs from SIR^2 dataset, containing three subsets (i.e., Objects (200), Postcard (199), Wild (55)).
