Digitizing - Study guides, Class notes & Summaries

UNIT I DIGITAL IMAGE FUNDAMENTALS 1.1. Define Image. An Image may be defined as a two dimensional function f(x,y) where x & y are spatial (plane) coordinates, and the amplitude of f at any pair of coordinates (x,y) is called intensity or gray level of the image at that point. When x,y and the amplitude values of f are all finite, discrete quantities we call the image as Digital Image. 1.2. Define Image Sampling. Digitization of spatial coordinates (x,y) is called Image Samplin...

Why Digitize Images correct answers - we live in a continuous tone world - no breaks between colours - colours seamlessly blend into one another - this is how our eyes see Graphic Communications is not continuous tone, but includes: correct answers - Pixels - Tone - Bitmap Image Capture correct answers The digitizing of images for use in the graphic communications industry 2 common ways we digitize images for graphic communications correct answers 1. Digital Cameras 2. Scanners...
