Scale-space pyramids

  Write an m-file "scale_space.m" which computes scale space representation of an input image for a given scale "sigma" and displays them.

(i) 4 scale levels, all the levels have the same size.

function scale_space(imn, sigma)

for i=1:3


(ii) 4 scale levels, every next level is twice smaller than the previous one.
To sample the image use:
Choose the sampling_step.

Discuss these representations.
How do they differ? Are they equivalent? Which one is more suitable? Why?
