SAMPLE QUESTIONS (IMAGE PROCESSING)

   1. 	Describe the fundamental steps in Image Processing

   2. 	What are the elements of a general purpose image processing system?

   3.	Show that the origin of the Fourier transform of f(x,y) can be
	shifted to the center of its corresponding N * M frequency rectangle
	by multiplying f(x,y) by (-1)^(x+y). (^ denotes power)

   4.	Establish the periodicity property of discrete Fourier tranform.

   5.	Given two functions obtain the convolution of them.

   6.	What is a band-limited function? What is Whittacker-Shannon sampling
	theorem?

   7. 	Given some functions, compute their DFT, Walsh, and other transforms.

   8. 	Explain the Histogram equalization method.

   9.	What are low-pass and high-pass spacial filters. Give examples of
	them.

  10.	Given some filter masks and a portion of an image, compute the 
	gray values of the filtered image.
