Self guided parameter w1

[olahugosson]

Hi Peter,

In section "7.16.2 Self Guided Filter Process" I'm wondering if

   v = w1 * u

should rather be

   v = w2 * u

Thanks, I've pushed a fix (note I think a different weight needs to be fixed).

(In my local version this was actually already correct, but I had forgotten to push the change back to the specification - many thanks for the reminder!)
