I'd try to rotate the wall so that it's perfectly vertical or horizontal. Then use movmean or conv2 to blur it. Then rotate it back to the original orientation.

It cent work, if i rotate the wall and the smoothing is on the Temperature i will do nothing beacuse T did not rotate with the wall, movmean do not take in to acount the new locations in T. that my problem.
