Document Scanner || A CODECLOUDS Community Initiative

Image processing/compression: Image processing involves that clean-up, cropping, straightening and compression of images. Bi-tonal TIFF Group 4 is still the most popular format for document image compression. However, the emergence of PDF and affordable color scanners have recently created some alternative imaging options. These include mixed raster content (MRC) formats where text and graphics can be separated and each compressed with optimum methods. PDF and JPEG 2000, Part 6 both support MRC compression.
