WebIn order to become suitable for digital processing, an image function f(x,y) must be digitized both spatially and in amplitude. Typically, a frame grabber or digitizer is used to sample and quantize the analogue video signal. Hence in order to create an image which is digital, we need to covert continuous data into digital form. There are two steps in which it is done: WebC) 3 only. D) 2 & 3 Only. When an image is extracted from a flat-panel detector the following occurs. Put the events in proper order. 1) Data is digitized by an analog-to-digital converter (ADC) 2) Data is read from the columns and rows, line by line. 3) A histogram is crated and analyzed by software.

A digital image is an image composed of picture elements, also known as pixels, each with finite, discrete quantities of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with x, y on the x-axis and y-axis, respectively. Depending on whether the image resolution is fixed, it may be of vector or raster type. By itself, the term "digital image" usually refers to raster images or bitmapped images (as op… WebA single image can be represented as a black and white image in a two dimensional (2D) array (matrix) of pixels having rows (i) and columns (j).
