I've just started looking at Eigen and it looks pretty cool - I am wondering how suitable it might be for common image processing operations, such as applying a filter. It's not immediately clear though how I'd do something like this, e.g. apply a 3x3 filter kernel to an MxN image?

This is an old post of mine...just to make you an example of convolution in eigen.

Thanks - it looks like cwiseProduct was the method that I'd overlooked.
