Any current text in Sensation and Perception will have what you want. Here
is a reference.
Coren, Stanley. (1989). SENSATION & PERCEPTION THIRD EDITION.

Everything you need to know is in chapter 4.

In many respects one could say that it has been figured out. Scientists
are always building on their previous theories though. I expect
spatial frequency analysis is something that will be studied for many
more years to come. Nothing is ever really "figured out" when it comes
to understanding the brain. Everytime a new insight is found another
question is added. Science is funny that way! ;)
