It does exactly that yes.

This is possible with what you call a convolution matrix, when you
convert from RGB to gray-scale. We could expose this convolution matrix
to the user of course, but the question is what would be the gain? I'm
no expert in this field, so I can't judge well on this. Perhaps you have
a resource or paper on this?
In the end it's also about, how complex you would like to make the lib
for usage.
