ABSTRACT

The equipment with which we capture images is often influenced by measurement noise; therefore the resulting images may not provide the quality needed for the desired analysis. In addition, even for images with acceptable quality, certain regions, features, or components of the image often need to be emphasized and highlighted. As an example, when processing medical images, highlighting certain parts of the image such as tumor-like regions often helps physicians make a better diagnosis. In this chapter, the main computational techniques commonly used in image processing to restore and enhance images are discussed.
