What does the level background process do?
The level background process analyzes all the images in a tile set and builds a pseudo flat-field correction image using the pixel data from the four corners of all the images in the tile set. It then applies the correction image to flatten the background portion of each image.
This process is especially useful when you have a tile set that was not scanned with proper flat-field correction.
This process works better for large image sets (more than 100 images). Smaller image sets may show signs of strange artifacts.
