Digital Image Processing Concepts

  • Euclid Seeram


This chapter outlines the essential concepts of digital image processing which is now prevalent in digital radiography departments. A definition of digital image processing is first introduced followed by a brief historical development leading to its use in medical imaging. Image formation and representation are reviewed through a description of the nature of analog and digital images, as well as image domains. Furthermore, the five classes of image processing operations are identified, and characteristics of the digital image are described. These include matrix, pixels, voxels, bit depth, and image appearance. The three steps in digitizing an image, scanning, sampling, and quantization, are briefly outlined. The chapter concludes with a brief overview of four image processing operations, point, local, global, and geometric operations, and offers a point of view on digital image processing as an essential tool for digital radiography technologists.
