Abstract
Much of what is now known about image manipulation and image-processing theory has been developed by those early researchers concerned with electrical signal processing. Images, when converted to electrical signals, were soon recognized to be a potentially fertile area for the extension of signal processing techniques. Early on, image processing was carried out on “analog” signals as opposed to numbers in a digital computer. Analog image processing was often performed using optical techniques or through the use of specially built electronic circuits which could perform specified functions. The term analog refers to systems and processes in which signals with uniform and continuous variations are manipulated. The term digital refers to systems and processes which involve manipulation of discrete numbers. Even in the case of digital images, the image information has exited at some point in time as an analog signal. To create the digital image, the analog signal must then be converted to discrete numbers and stored in a computer memory. This conversion process is called analog-to-digital conversion (ADC).
