Different Techniques Used for Image Processing

Analog image processing is a process of processing of images by electrical means. Example of such processing is television images. As the television signal is a voltage level, hence they vary in terms of amplitude in order to represent brightness by means of image. Displayed image appearance can be altered by varying these electrical signals. The brightness and contrast controls on a TV set serve to adjust the amplitude and reference of the video signal, resulting in the brightening, darkening, and alteration of the brightness range of the displayed image.

Image processing usually refers to digital image processing, but optical and analog image processing are also possible. This chapter is about general techniques that apply to all of them. Medical imaging is the technique and process used to create images of the human body for clinical purposes or medical science. Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are not usually referred to as medical imaging, but rather are a part of pathology.

In general, image processing entails modifying a picture to improve it or extract information from it (Hesselink 1988; Seul et al. 2000; Wang et al. 2018). Image processing can be done in two ways, analog image processing and digital image processing (Billingsley 1970; Dougherty 2020; Hord 1982; Kuruvilla et al. 2016; Solomon and Breckon 2011). Physical film-based photographs, prints, etc., are associated with analog image processing while computer algorithms are used to manipulate digital images in digital image processing (Basavaprasad and Ravi 2014; Burger and Burge 2016; Kuruvilla et al. 2016).
