In today’s information society, processing of digital images becomes a key element for interaction with our environment and for transport of important messages. Consequently a huge effort has been undertaken in developing algorithms for image enhancement, transformation, interpretation, and compression. Whereas in the past computational capacities have shown to be the limiting factor, the recent progress in design of semiconductor devices allows implementation of powerful algorithms. Corresponding examples can be found in constantly increasing function ranges of cellular phones, in various types of object recognition, in complex acquisition of volumetric scans for medical imaging, or in digitization of production, transmission, and projection of cinematographic content.
