Abstract: The concept of Mixed Raster Content describes a compound document image as being composed of several layers, each containing a part of its visual information. Usually, three layers are sufficient for classifying the types of content present in such an image: a foreground layer, a background layer, and a mask layer. In this context, MRC-based compression schemes promise to be more efficient than classical ones (where a single algorithm is used to compress the entire image), due to their implicit content-adaptive nature, because each layer can be compressed separately with a suitable algorithm (JPEG, JBIG etc.).
