Possible memory leak?

[Tuvas]

The reason it's done in width and heigth is that there is some other
non-related processing functions that were going on in the mean time
with the problem. I found the source of the slow-down, when 2
non-important lines of code were commented out, the program worked
perfectly.

                         if(vfilter.get() and d_filter and filt):
                                num=round((num-(d_filter[index/2])))

I don't know why these lines of code are causing a slow-down, but, it
is for some reason. What I will do is just simply combine these 3
variables (Which won't move image to image) into one variable, that
will not have the problem that I've seen. But, thanks for all of your
help!
