Image Processing , Technology & Science / October 16, 2017

Digital image processing is concerned primarily with extracting useful information from images. Ideally, this is done by computers, with little or no human intervention. Image processing algorithms may be placed at three levels. At the lowest level are those techniques which deal directly with the raw, possibly noisy pixel values, with de-noising and edge detection being good examples. Digital image processing : Definition Digital image processing is the manipulation of the numeric data of the digital image for enhancing it to make it suitable for the further processing according to the specific application needs. Today, Image Processing systems are very popular due to easy availability of powerful computers, large size memory devices, graphics software etc. By doing image processing, corrupted pictures can be enhanced, medical images clarified, and satellite photographs improved. Image Processing is a technique to enhance raw images received from cameras/sensors placed on satellites, space and aircrafts or pictures taken in normal day-to-day life for various applications. A digital image is an array of real numbers represented by a finite number of bits. Basic operation of image processing can be shown with the help of figure 1. Figure 1: Basic Operations While acquiring the image from the source…
