Question 2: 15 marks

  1. Briefly describe what Digital Image Processing (DIP) operation is appropriate to achieve the following effects/results:
  1. Reducing the size of an image from 128x128 pixels to, say, 64x64 pixels by using an appropriate image size reduction technique that uses minimum number of coefficients that you have studied in this course. Will it provide similar quality result as compared to a technique using larger number of coefficients and why? Write the relevant equations in both cases in their general form. 6 marks
  2. It is desired to enhance a dull/unclear image and make it clearer. What DIP operation is appropriate for this purpose and why? 4 marks
  1. Find the storage requirements for storing a UHDTV-2 video of 15 minutes duration using standard frame rate and using 7680x4320x24 bit image pixel array. 5 marks
