counting pixels of an object

I am new to programming my first app was a rather simple app that is a moderate success in itunes and amazon.
I am not sure if there is a way to do what I a attempting now but I want to calculate the pixels of an object that I take a picture of say my hand against a dark background for instance.
I know that this is a tall order. I am not sure if its possible.
Any input appreciated.
Thanks

Hi.

Welcome to Corona!

Currently, there is no way to look at individual pixels using Corona.
