receptive field of view for clustering was not correctly updating according to input image size - fixed

Hi,
I've had problems with detection on images with greater height than training images, and images with greater height then width. For example here, I have trained the net on images with halve the height than the tested one and the net was able to find only the top row objects.

After applying my change, I can work with any image size with no problems:

I have been using this patch for few years now, so it's tested on many cases.
Nobody else seems to have noticed this so maybe I'm doing something wrong - in this case please guide me to find my mistake. Thank you.
