Problem 1
(b)
Output file: bus1out.pgm
K = 0.009

(c)
Output file: bus2out.pgm
K = 0.08
The goal here was to do a deblurring of the bus without introducing artifacts.
If you want to get the bus a little bit sharper, you have to choose K = 0.001.
To see, what's the result with K = 0.001, you can have a look at bus2out2.pgm.

(d)
Output file: hogblurout.pgm
K = 0.005
The runtime is longer, because the FFT has a higher runtime. This is due to
the fact that the image hogblur.pgm has a size of 240x320. Both, 240 and 320
are not a power of 2. From the lecture (Lecture 4, slide 18), we know that
the FFT requires a signal of size M = 2^k.
Furthermore, k-motion.pgm has a size of 40x21. Both values are also not a
power of 2 which increases the runtime of the whole computation again.
