  Question 1. Define Image? Answer : 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. Question 2. Define Image Sampling? Answer : Digitization of spatial coordinates (x,y) is called Image Sampling. To be suitable for computer processing, an image function f(x,y) must be digitized both spatially and in magnitude. Question 3. Define Quantization ? Answer : Digitizing the amplitude values is called Quantization. Quality of digital image is determined to a large degree by the number of samples and discrete gray levels used in sampling and quantization. Question 4. What Is Dynamic Range? Answer : The range of values spanned by the gray scale is called dynamic range of an image. Image will have high co...
