The Origins of Digital Image Processing & Application areas in Digital Image Processing Medical Images

Abstract

One of the first application of digital x and y are spatial (plane) co-ordinate, and amplitude of f image was in the newspaper industry, when picture at any pair of were first sent by submarine cable between London co-ordinates(x, y)is called the intensity or gray level of the and New York.Introducation of the Bartlane cable image at that point. When x, y and the amplitude values of picture transmission system in the early 1920s f are all finite, discrete quantities, we call the image a reduced the time required to transport a picture digital image. The field of digital image processing refers across the Atlantic from more than a week to less to processing digital images by means of a digital than three hours.Spaecialized printing equipment computer. A digital image is composed of a finite number of elements, each of which has a particular location and coded pictures for cable transmission and then values. These elements are referred to as picture elements, reconstructed them at the receiving end. Some of the image elements and pixels. Pixels are the term most initial problems in improving the visual quality of widely used to denote the element of digital image these early digital pictures were related to the . selection of printing producers and the distribution of 2.The Origins of Digital Image Processing: intensity levels. In facts ,digital images requires so much storages and computation power that progress in the field of digital image processing has been dependent on the development of digital computers IJERT IJERT One of the first application of digital image was in the newspaper industry, when picture were first sent by submarine cable between London and New York.Introducation of the Bart lane cable picture and of supporting technologies that include data transmission system in the early 1920s reduced the time storage, display and transmission. The digital image required to transport a picture across the Atlantic from is composed of a finite number of elements, each of more than a week to less than three hours.Spaecialized which has a location and values. These elements are printing equipment coded pictures for cable transmission referred as picture element, image element &pixels. and then reconstructed them at the receiving end. Some of Pixels used to denote the element of a digital image. the initial problems in improving the visual quality of The process of acquiring an image of the area these early digital pictures were related to the selection of containing the text, preprocessing that image, printing producers and the distribution of intensity levels. extracting the individual characters , describing the In facts ,digital images requires so much storages and character in the form suitable for computer computation power that progress in the field of digital processing & recognizing those individual character image processing has been dependent on the development of digital computers and of supporting technologies that are Digital Image Processing.
