2015-08-16 11:30:03 -0600	commented question	distance between images, pixel by pixel I'm implemented painterly rendering for a project. One of the steps is the calculate the distance between the source and a blurred image in a pixel by pixel manner, then sum square regions of the distance map to make decisions. I found the sum of the regions in a Mat using `operator()` and `sum` -- I'm hoping that the distance map can be found as a Mat then.

2015-08-16 11:10:15 -0600	asked a question	distance between images, pixel by pixel I'm need to calculate the euclidean distance between two `cv::Mat` images in a pixel by pixel manner. Is there a function that does this? Specifically, I need the result to be of the form `diff[i] = sqrt( (r1-r2)^2 + (g1-g2)^2 + (b1-b2)^2 )` where `diff` is a `Mat`. If there is no function, is there a simple way to calculate this? Thanks!
