Digital Image Processing, Third Edition

Digital Image Processing, Third Edition Digital image processing is all about images, definitions, and algorithms. First it is necessary to define two terms: digital images and digital image processing. In this textbook we read that an analog image is a two-dimensional function of spatial plane coordinates x and y and an intensity at each point. When the spatial coordinates and the intensity at each point are finite discrete quantities, then the image is defined as a digital image. Digital image processing is the processing of digital images with a digital computer. Each digital image is composed of a finite number of elements, each with a particular location, called pixels. Digital image processing is an important technique for scientists and engineers who acquire, manipulate, measure, compare, restore, compress, analyze, and data mine images. One interesting feature of a digital image is its scale invariance—an infrared image of a galaxy, a magnetic resonance imaging MRI image of the brain, an optical microscope image of cells, an electron microscope image of nuclear pores, and an atomic force microscopy image of gold atoms on a graphite substrate all differ in scale, but they all can be subjected to the techniques of digital image processing. A second feature is the ubiquitous nature of digital image processing. Readers of the Journal of Biomedical Optics JBO should be familiar with digital images that are acquired with a microscope or an endoscope. In the field of medical imaging, images acquired with MRI, ultrasound, x-ray, and positron emission tomography techniques are subjected to image processing for enhancement, segmentation, measurement, and compression. The key point is that digital image processing can be applied to any digital image. This is a true statement and is not dependent on the scale of the image, nor on the type of instrument that is used to obtain the image. Digital images are acquired, digitally processed, and displayed. The human eye and the visual system enter the domain of digital image processing since visual perception is an important component of the process as well as the subjective assessment of image displays.

I highly recommend Digital Image Processing, Third Edition as an outstanding textbook, and I will provide the reader with the basis of this conclusion. Additionally, there is a companion book, Digital Image Processing Using MATLAB, by Gonzalez, Woods, and Eddins that was published in 2004. In 1977, Gonzalez and Wintz published the first edition of Digital Image Processing, and the second edition was published in 1987.
