This dataset consists of 2579 image pairs (5158 images in total) of wood veneers before and after drying. The high-resolution .png images (generally over 4000x4000) have a white background. The data has been collected from a real plywood factory. Raute Corporation is acknowledged for making this dataset public. The manufacturing process is well visualized here: https://www.youtube.com/watch?v=tjkIYCEVXko.
There are two folders: "Dry" and "Wet". The "Wet" folder contains wet veneer images and the "Dry" folder dry veneer images. The files are numbered so that e.g. Wet_10 is an image of the same veneer as Dry_10, but the veneer has been dried in between.
