Radial hash ignores gamma parameter?

[ChernyshevDS]

Looking at ph_image_digest function, I've discovered the following line:

(graysc / graysc.max()).pow(gamma);

It seems for me, that this line doesn't do anything, because graysc.max() returns scalar value, and operator/(const T value) returns new image instance. pow method is called on that instance, but it doesn't make any difference, because the result is not assigned anywhere.
Am I missing something there?

You're right - that looks like a bug
