It works well with a smaller region. But now I have the problem of not
"dehazing" the whole scene. Is there any simple way of dehazing the
whole scene or will I have to do something like cut, dehaze and put
together again?

I will probably not need to dehaze the whole scene for the work I'm
doing now, but for the future this might prove necessary.

Is this a bug of r.linear.regression? Would this bug fix be very
complicated?
