Combining Image Matrices
Hi there, I wanted to know if someone could explain to me how are image matrices (given to be of lower resolution) "merged/combined" to create another of greater size (thus resolution as well). For instance, if I have 4 matrices that are 144x144 and from these I would like to get a 576x576 image. I tried doing puffing ... 9 Feb 2010 15:07
