Hello there. I recently discovered that qt had good GUI systems at worked well with opencv. Naturally I rushed to try it. I discovered that there were even precompiled libraries and binaries for mingw. Now, considering the fact that I have never used qt before, I just did what the last parts of the tutorials said (the parts after cmaking the libraries and building them). Unfortunately, the qt environment cannot find the library files. It says it cannot find the libraries hat I am including and that they do not exist. ( I have had this problem with visual studio too but I resolved it with proper path declaration)

the tutorial I mainly used was this one.

As far as I understood I had only to include the bin folder in the system path and then add the libs and include paths. I obviously replaced their directories with their equivalents in my system, and I replaced 231 in each include with 245. Now, is there anything that I missed? Is it absolutely imperative that I compile from source to make it work? I would appreciate any light anyone can shed on the matter.

I would like to have my entire interface in one window for personal reasons. I have already figured out how to place the images in the same place, but trackbars are another issue. Is there any way to control their placement in the window or would I have to modify the openCV library to do so?

I noticed that QT seems to do the job for many. Is there a way to use it while still avoiding cmake? (it hasn't been working lately so I have fallen back on precompiled binaries).

aah. i see. I was wondering why the thresholding operation was not taking up all four cores. It seemed natural that this operation would multithread. It seems that it just doesn't take many resources to do, so the effects were not noticeable. I tried repeating the threshold 100 times in a for loop and lo and behold, all four cores were being used. Thank you for making this known to me, that opencv already multithreaded,

I am sort of new to this, so excuse me if I make any obvious mistakes. I recently found that my tracking code does not work very well on older computers. So naturally I looked to parallelization. Unfortunately, I use prebuilt libraries, and thus am unable to use tbb. (cake was giving me issues) however, I read that recently, in 2.4.3, concurrency was added into the opencv library. my question is, how the heck do I use it?
