Problem:
----
We considered shared memory when optimizing our kernel. When attempting to implement shared memory we realized that it would be a difficult task to complete because every pixel in a block needs access to a different range of pixels for averaging. One major problem was that neighborhood pixels may fall out of range of the block. We also attempted to store the entire image in shared memory but this solution is not salable scalable to larger image sizes as shared memory is a limited resource.

Below you'll see that our optimizations although show slight improvements sometimes, it was not effective. We are currently still looking for a way to implement shared memory which will surely improve efficiency and execution time.
