How can I select the 4-neighbours of a pixel in matlab?
Thanks.
If the the image is img and the current pixel indices are i and j, then the four neighbors will be:
img(i-1,j);
img(i+1,j);
img(i,j-1);
img(i,j+1);

I'm studying computability theory, and I'm looking for a problem that clearly can be solved, but not in polynomial time.
I tried thinking of all sort's of examples, but it wasn't clear why they can't be solved in polynomial time..

I've also been asked to use diagrams if appropriate but that's a little hard on here I understand.
Here is a PDF presentation which describes insertion sort.

how can I build a balanced quad tree.
Thanks, Marcos
Balancing is traditionaly a part of "k-D Tree" algorithm, which is superset for octrees. Try e.g. wikipedia page on this algorithm.
