Preprocessing medical images and their overall enhancement

This chapter briefly discusses the main stages of image preprocessing. The introduction to this book mentioned that the preprocessing of medical image is subject to certain restrictions and is generally more complex than the processing of other image types [26, 52]. This is why, of the many different techniques and methods for image filtering, we have decided to discuss here only selected ones, most frequently applied to medical images and which have been proven to be suitable for that purpose in numerous practical cases. Their operation will be illustrated with examples of simple procedures aimed at improving the quality of imaging and allowing significant information to be generated for its use at the stages of image interpretation.
