Assignment 2 - Two questions
1) In problem 1 we have to implement a function upsample2 which should make use of a binomial filter after the upsample step. However, no treatment of boundaries is specified. I see two options here, either a standard convolution or a matlab image filtering method choosing one of the boundary treatment options. Should we just use the one which we find best? Either way, results may differ depending on the chosen method.
2) Subtasks of problem 1 and problem 2 involve the display of matrices in range [a, b] where a is negative and b is positive. Again, there are various options here. My preferred solution would be to normalize to the range [0, 1] such that the 0 in range [a, b] now corresponds to 0.5. If we ignore the zero, however, results look brighter. What do the teaching assistants prefer?
Thanks in advance!
