1 Digital Image Processing Module 1 Module 1 DIGITAL IMAGE PROCESSING An imageis defined as a two dimensional function, f(x,y), where x and y are spatial (plane) coordinates, and the amplitude of ‘f’ at any pair of coordinates (x,y) is called the intensity or gray level of the image at that point. A digital image is a 2D representation of a scene as a finite set of digital values, calledpicture elements or pixels or pels. The field ...

Fundamental steps in Digital Image Processing • ImageAcquisition This is the first step or process of the fundamental steps of digital image processing. Image acquisition could be as simple as being given an image that is already in digital form. Generally, the image acquisition stage involves preprocessing, such as scaling etc. • ImageEnhancement Imageenhancementisamongthesimplest and most appealing areas of digital image processing. Basically, the idea behind enhancement techniques is to bring out detail that is obscured, or simply to highlight ...
Study electronics and Communication Engineering https://buzztech.in/ Fig: Fundamental steps in digital image processing 1. Image Acquisition: In image processing, it is defined as the action of retrieving an image from some source, usually a hardware-based source for processing. It is the first step in the workflow sequence because, without an image, no processing is possible. The image that is acquired is completely unprocessed. In image acquisition using pre-processing such as scaling is done. 2. Image Enhancement: It is the ...
