Subsampling a matrix
Posted:
Jul 23, 2012 7:09 AM


Hello! I would like to simulate the effects introduced by finite sampling of an image. To do this I compute a very large matrix with a large number of elements. Then I want to subsample it to the actual pixel size of my "sensor". Which way would you reccomend to do this? I would think that I should be summing all the values of the element in my "HIRES" matrix that go in one element of my new "LORES" matrix. Am I correct? If so... Is there a matlab function to do this?
