CSE166 – Image Processing – Final Instructor: Prof. Serge Belongie http://www-cse.ucsd.edu/classes/fa06/cse166 11:30am-2:30pm Tue. Dec. 5, 2006. On this exam you are allowed to use a calculator and two 8.5” by 11” sheets of notes. The total number of points possible is 58. Good luck! Part I: Fill in the Blank (1 pt. each, 20 pts. total). 1. The Fourier transform of a Gaussian is a(n) . 2. If a function is narrow in the spatial domain, then it is in the frequency domain. 3. I ( x,y ) is computed in Matlab using the function . 4. Given a function f ( x ), the M -point DFT F ( u ) evaluated at u = ( M/ 2) + 1 is also known as the -component. 5. The binomial function is the discrete approximation to a function. 6. A neighborhood of an image where half the gradient vectors equal ( ± 1 , 0) and the other half equal (0 , ± 1) is an example of a rank- neighborhood. 7. The values u and v satisfying the equation I x u + I y v + I t = 0 in a small window represent the . 8. The convolution of an
