Hello, this is probably pretty straightforward, but I am very new to OpenCV.

I have a camera frame grabber application where the user is allowed to "average" N frames into a single frame (as a way to reduce signal to noise ratio)

So I have 3 (or N) Mat's all the same size (16bit grayscale) and I want to combine them all into one such that the result is the "average" of the 3.. So this isn't really a blending of unique images, each frame is going to be nearly identical, the goal is to average them to reduce the signal to noise.

What's the best way to do this?

Thanks

edit: I tried cvAccumulate, but it fails, I'm thinking because the documentation says it works only for 8 or 32bit images.

I did make this work by brute-force (non OpenCV) looping, summing, averaging and then setting those values into my final/averaged matrix.. but is there a better way with OpenCV?

Thanks
